Check all parts supplied in the hho kit before starting assembly in the cold front of the vehicle.

For proper installation and operation of the kit, you can upload pictures and a short videos up to 10MB via new online chat before starting the engine to guarantee the warranty. If the damage is caused by improper installation or modification, the contract becomes void. We take no responsibility for adding additional components to the engine's combustion chamber, failure to achieve the expected result or the condition of the engine and vehicle. We are always happy to advise for free.

New H2 and HHO kit has multiples more load if the mount is under the hood with temps around 50°C and above. We can't guarantee reliability if the hho kit with accessories was generating excessive heat without cooling and mounted in the wrong place under the hood and overheated. Only in front of the radiator where it is cool is a mount with extended life allowed.

In dry climates such as Australia, Spain, North Africa, Mojave or Mexico, use an external bubbler mounted outside the engine compartment for maximum cooling of the HHO gas, not under the hood. If you live in a humid climate such as Japan, Germany or Canada and with frost, do not use a bubbler in winter without Isopropyl alcohol.

Watch videos with H2 and HHO Kit installations

Just Fit & Plug-N-Go Video & Manual. Follow Diagram, manual, and watch new videos. 

Before any operation on the system, watch videos and read the manual below.

  1. ⚙️ Under the hood, where it is more than 50 ° Celsius (122° Fahrenheit), it is recommended to store all electronic devices in a cool place away from the engine where it is over 80 ° C and in summer from the hot hood up to 100 ° C.

    ☀ We recommend installing in the cargo space of the vehicle only in areas where temperatures do not drop below freezing point. The presence of condensed water in the pipe between the HHO bubbler and the air intake to the engine can lead to its freezing at low temperatures.

  2. To avoid overheating carefully, you could try mounting the hho kit under the hood in the coolest place with easy access for topping up 60ml of water every 3000km/7w in iX5 MK4 with thin cable between PWM and HHO generator. The bubbler must be mounted in the front grille in front of the radiator to prevent evaporation even over the summer. Need easy access for any winter maintenance to top up antifreeze isopropyl alcohol. Hho gas from the bubbler entering the engine must be super dry without a single drop.

  3. Installation Guide for the New Vibration Sensor for the Start-Stop 5-pin Relay:
    1. Select the coolest location on the engine, ideally a spot that doesn't exceed the temperature of the surrounding air and is comparable to human skin temperature.
    2. Potential mounting locations include:
      • Vibrating intake hose
      • Intercooler
      • Electrical cables
      • Support structure
    3. Before installing, ensure that the chosen location is not overly hot. Use your hand as a gauge - if the location or the air flow from the engine isn’t too hot to touch, it's suitable for sensor installation.
    4. Follow the instructions to mount the sensor at the selected location.

    Warning: Ensure the sensor’s mounting spot is not exposed to excessive heat or other adverse conditions that might affect its functionality.

  4. Guidelines for Installing Older Versions with the Smart Relay, which includes Water Level Control, WiFi PWM Control, and the Watts Amps LCD Display:

    1. Choose a location that is well-cooled and dry. This will help prevent the system from constantly activating due to unfavorable conditions.
    2. When using the Smart Relay, we advise the following steps:
      • Turn on all vehicle lights.
      • Activate the radio and air conditioning.
      • Monitor the voltage while these are running. Should the voltage drop below 13.3V, it indicates the start-stop system should be engaged.
    3. If needed for optimal placement, you have the flexibility to extend the red fuse and the grey cable.
    4. Optionaly: If you have an LCD for the dashboard with 1-2 m cables it can be connected between the WIFI and the black extension cables for the PWM.

    By adhering to the above guidelines, you will greatly prolong the lifespan of your equipment and mitigate potential issues related to its operation. We understand the significance of maintaining your equipment's prime condition, and these recommendations are meticulously curated to ensure just that.

    4. Follow the instructions to mount the sensor at the selected location.

    Warning: Ensure the sensor’s mounting spot is not exposed to excessive heat or other adverse conditions that might affect its functionality.

  5. If HHO kit with PWM is assembled under the hood, fit the PWM down under the hho kit where it is the coolest or front before or beside cooling radiator. In the summer, heat above 50°C can damage the PWM, even when parked. 

    Follow Diagram how to connect PLUG-N-PLAY cables. Never connect cables from a power source over 2.2V as battery/charger 12V/24V+ directly to the central HHO Kit unit otherwise the HHO Kit central unit will be damaged, and the warranty will be void. Find a cool place like we did in the picture.

  6. How should I adjust the wattage of my HHO system based on my engine size and the type of fuel I use to optimize fuel consumption and reduce emissions?

    To optimize fuel consumption, we typically suggest adjusting your HHO system to function at 5-7 watts. For contemporary fuels labeled as Diesel B7+ Eco corn or Petrol E10+, here's our wattage recommendation based on engine size:

    • 1 Liter engines: 25W
    • 2 Liter engines: 35W
    • 3 Liter engines: 45W
    • 4 Liter engines: 55+W

    If you're driving older vehicles without DPF or GPF filters and aim to diminish emissions to achieve nearly odorless exhaust, consider a setting of 15-22+ watts. Not only does this help in emission reduction, but it also prolongs intervals between water refills, cutting down on maintenance efforts and elevating the system's user-friendliness.

  7. You can use customised cables between the PWM and the HHO generator for optimal HHO system setup. Using the WIFI remote control, you can fine-tune the output of your HHO system from 0 to 30W.

    Can I change the length of the thin cable connected between the PWM and the HHO generator and modify it for experimentation?

    If you modify the HHO generator to a higher current, there will be a conflict with the thermodynamics of the engine and can reduce emissions in diesel engines, but fuel consumption, and performance will be worse, and the range of 3000-6000 km per water refuelling will be radically reduced to 1000-1500km in small slim iX5.

    Modification for experimentation will result in the loss of the ten-year warranty.

  8. Connect water level sensor plugs to smart relay.
    And here's a crucial tip: Always make sure to connect the water level sensor plugs to either the engine vibration sensor or older version with the smart relay. If you miss this, your system won't function correctly. Think of it like plugging in headphones – without the connection, you won't hear any sound. So, always double-check this connection!

  9. When fitting the generator, it is important to do so carefully and with precision. After positioning the generator in between the grill/mask and cooler, securely fasten it in a vertical position. Once all connections are secured, VERY CAREFULLY SLOWLY close the bonnet/hood to establish the clearance between the hood and hho generator. This process should be done with extreme caution, as sudden movements and jerks can result in damage to parts.

  10. Once fitted, it is important to ensure that all components of the generator are operating correctly by testing with a built-in 4-in-1 LCD ammeter blue LED or any WATTS meter. This will allow you to measure exactly how much power your system is producing; aim for at least 5-7 WATTS for optimal performance. If power readings don’t meet this level, adjustments may need to be made in order to increase the efficiency of your generator. Additionally, doing regular maintenance checks on your system will help to keep it running at optimal levels and reduce any potential risk of future issues arising from using an insufficiently powered hho generator.



    Using a syringe and adapter, pour in deionized or distilled water with a TDS of 0.

  12. ATTENTION FOR IX 5, 10, 20 WITH KOH 90-95%:

    Using a syringe and an adaptor, pour deionised water into 500ml strong plastic or glass deep dish or vessel. The amount of deionised water and KOH 90-95% for each HHO generator can be found in the table below.

    Gently add KOH 95% to the water and stir slowly and carefully until all of the solid has dissolved. Make sure to wear protective gloves, goggles, and clothing when handling KOH 95%, as it is caustic and can cause injuries if not handled properly. Allow the solution to cool completely before moving on to the next step.

    Notice: 250ml of dry KOH 95% is exactly 250g of dry KOH 95%. It depends if you use a syringe or a scale.

    Once cooled, the electrolyte will be ready for use for up to one year in both hot summer temperatures up to +50°C in the shade and cold winter temperatures down to -60°C. Using a syringe with an adaptor attached, slowly draw out some of the cooled electrolyte from the plastic cup into the syringe. Carefully pour this electrolyte into the stainless steel 316 fitting at the top right in small amounts until it is full. Finally, securely seal off the hole using a blue nylon push-n-go end cap so that none of the electrolyte escapes or gets contaminated over time.

  13. Do I need to add KOH or NaOH again the next time I refill the water?
    With maximal concentration of KOH 90-95% or NaOH 98% at the next refill, add deionised water only for approx. 1 year.

  14. Never add other substances such as baking soda, salt or antifreeze. All of these will create unwanted foam and will need to be carefully removed with clean water to prevent foaming. Never use detergents or any alcohol to clean the generator, only clean water.

  15. How to hack water to stop foaming? Large unwanted foam sometimes come
    The easiest solution is to mix deionized water with the maximum amount of KOH 90-95% or alternative NaOH 98-100%. Wtach video.

  16. How do you keep the solution from freezing in -30°C -60°C, -22.0°F -76°F Canadian winter temps? Without antifreeze and maximum KOH 90-95% until crystallization is ready to -60°C / +50° C. This benefit is possible with the iX hho kit Celtic Tiger heavy-duty waterproof PWM only.

    Whenever a severe frost is to come below 10-25°C, and you do not know how to prepare the hho main unit under -30% -40%, disconnect and remove the portable hho kit to prevent damage, contact us, and we will be happy to provide you with information for free.

    The electrolyte with dry KOH 90-95 % 10 ml to 30 ml, depending on the volume and type of the hho kit, is set to approx. -10 / -15°C. When an additional 30 ml of dry KOH 90% is added for 100 ml of water, the electrolyte does not freeze up to -30°C.

    You can try it first in a small cup stored in the freezer.

  17. Can I leave bubbler empty? You can leave the bubbler empty, and if it starts to steam, the electrolyte solution will settle into a liquid of minimum volume. This is because HHO gas production in the iX generation is designed to be very efficient and reliable at producing an optimal amount of HHO gas with minimal overheating or other issues as in other hho generators. This is thanks to its design which allowes it to fit in the front of the car where there is direct access to fresh, cold air from outside. The cooling air help regulate temperature and keep the hho generátora nad 25°C from overheating due to the high levels of heat generated when producing HHO gas. Thanks to this advanced design, power and fuel efficiency are improved without negatively impacting performance or safety. Additionally, due to its efficient cooling system, the life expectancy of components within the iX generation system is increased significantly compared to traditional systems.
  18. Methods of running an external bubbler in winter.❄️

    If you live in a climate with freezing winters, we recommend using an external bubbler only in the summer. If you live in a climate with high air humidity above 60%, we recommend disconnecting the hydrogen supply and connecting the hho pipe directly to the intake manifold. Keep the bubbler empty.

    You have a device called an HHO generator. This device needs to be filled with water to function properly. When you add water to it, I recommend gently tilting it to the left side. By doing this, the water will move into a part of the device called the "bubbler".

    This water is special. It is mixed with KOH 90-95%, creating a super-strong electrolyte that can withstand extreme temperatures as low as -60°C and is also comfortable with temperatures up to 50°C in the shade. But if you notice there's too much water inside the device, you can use a syringe (without the needle, where the blue pin usually is) to draw out the air from the generator. When you do this, the water from the "bubbler" will return to the HHO generator's reservoir. This is important to ensure that there is the right balance of water and necessary space inside the device for it to function optimally.

  19. An alternative to non-freezing water in external iX bubblers? ❄️
    Add 99.99% isopropyl alcohol as an additive for iX bubbler antifreeze and detergent if the temperature falls below -30 to -50%. Water-isopropyl alcohol mixtures have depressed melting points. Isopropyl alcohol becomes increasingly dense with decreasing temperature and freezing at −89 ° C (−128 ° F). Isopropanol is ideal for degreasing and cleaning natural household products, solvent for crystallisation in antifreeze, washer additives, sweat layer, and fat layer to remove artificial nails and much more.

  20. OPTIONAL One-way check valve.

    The one-way valve interrupts the smooth flow of HHO gas under 20 watts. For better gas flow, we do not recommend blocking the passage. It serves only to stop the water from the bubbler from returning to the hho generator. 

    Before plugging the fuse or starting the engine, ensure that the hose is not blocked by ice, a wrong one-way valve position, or a broken hose caused by improper installation. Blocking the output for hho gas irreversible destroys the hho kit main unit and cannot be replaced for free or refunded!! 

    For proper installation and operation of the kit, you can send us pictures or a short video before starting the engine to guarantee the warranty. If the damage is caused by improper installation or modification, the contract becomes void. We are always happy to advise for free.


  22. TUG TEST Clear Teflon Hose at each fitting. If it separates from the connector, it must be re-fitted by pushing 8mm of exactly hose minimum firmly into the joint.

  23. RE TUG TEST Albright hose fittings if any failures occurred.

  24. Installation 1/4" BSPT or NPT fitting for the pneumatic hose to deliver hho gas 7W before the Air intake and before MAF sensor as in Lexus and Mercedes videos ( we do not recommend behind MAF sensor): The screw tap can be BSPT or NPT 1/4 "-19, drill size 29/64 inch or 11.5 mm. If you do not have a screw tap, drill a hole larger than 11.8 mm and use a red or black sealant to seal the engine head.

  25. Re-start the engine, and: Check that the hho generator is generating bubbles of hho gas and in the bubbler's clear window.

  26. Re-check that the Teflon pipe from the top of the bubbler is still installed inside the engine air intake pipe before air filter box at the front bottom of the battery, almost as far as the air filter housing.

  27. Gently TUG TEST all the wiring connections and plugs & Check that no wires or hoses are too short. Ensure sufficient insulation is stripped to make a good connection with the copper core of the cables.

  28. CAREFULLY close the hood gently and slowly, and check that clearance exists (5mm Minimum) between the hood and any fittings, components, and wiring.

  29. For proper installation and operation of the kit, you can send us pictures or a short video before starting the engine to guarantee the warranty. If the damage is caused by improper installation or modification, contract becomes void. We are always happy to advise for free.

  30. Test drive your vehicle for a minimum of 10 Km and optimal 150km with HHO chips.

  31. Switch off the engine, apply the parking brake, Open the Engine bay hood, and inspect the installation for secure mounting of all components, loose bolts, insecure hose routing, vulnerable wire routing, and unstable plug connection to the wiring.

  32. Re-start the engine and check Gas bubbles are being generated, as viewed in the hho generator window.


How to drive economically and achieve the same maximum fuel economy with iX ADVANCED PREDATOR as in our videos?

It is essential to ride radically economical with a light foot, just like in the videos. A minimum current of say 5-7 watts at about 0.5 A@14V is required. Otherwise there is little, no benefit or may be worse due to a contradiction in the law of thermodynamics.

Every vehicle, even of the same type and year, is unique, so it all depends on the owner and the condition of the vehicle. We therefore recommend finding a suitable location for the HHO gas supply. We recommend the HHO inlet before the air filter with 7 watts or later with more watts after the MAF sensor, if necessary. This will ensure the purity of the intake gas with air neutralization. If the vehicle control unit correctly evaluates all the data from input to output sensors in the exhaust everything is better. In some cases, changing the position of the HHO inlet after the MAF sensor in the intake manifold will help customers, resulting in an increase in dynamics, but the reduction in consumption may be minimal or worse.

(negative ions converted from the infrared radiation of the engine - no magnets!)

QUICK INSTALLATION OF HHO REDUCE ENGINE FRICITON TUBES FOR HHO KIT (negative ions from infrared radiation from the engine - no magnets!)
Fit all blue HHO REF tubing to cross over the injector microtubes, common rail inlet and large tubing around the fuel filter inlet and fuel pressure pump inlet on the diesel version. For best results you can use lead tubing first. Everything must be as shown in the pictures otherwise maximum effect may not occur!!! Even with a small precise change, -0.1L/100km can be a success to achieve up to -1L/100km fuel economy.

See the Latest Videos Showing Fuel Savings of 20-36% on Highways, City Roads, and More!

Every time if you make a minimal change to the tubes, even moving the tube 1 cm or covering it with lead, the hho chip should be reset and drive minimum 8km and 30-50km to see new result. There is a significant change in the engine!
Slide the brown tube cut into several parts onto the bent hose. Never cut off any engine tube or parts. 
Use all tubes to cover the end of the fuel pipe close to engine parts as is fuel filter, pressure pump, injectors.




Does the new HHO REF work well with the iX HHO Kit?
Absolutely yes, we have modified the tubing and lead sheets to fit the fuel line for all types of motors. Don't worry, everyone is very satisfied with new HHO Kit + HHO REF+ HHO CHIP EFIE. At 80 km/h is 5.3 l/100 km versus 74 km/h 5.5 l/100 km. When the speed is higher with more power there is better fuel economy. The higher temperature and infrared radiation from the engine produces more energy for frequencies in REF materials.

Can low temperature limit the function of REF?
At low temperatures under 0 °C, the function of the tubes in the petrol and diesel engines may be limited. When the engine is heated to 80-100 °C (The best is 500°C), the tubes start to receive infrared radiation from the engine and the fluid molecules start to shrink, which has a positive effect on reducing engine friction.

Fuel pressure pump, diesel fuel filter, breaking fluid pump, steering wheel pump all these parts create load and friction on the engine. By connecting more tubes, further percentages of powerare obtained, resulting in reduced consumption and harmful emissions.

Tips on how to maximize engine efficiency with the iX HHO KIT+HHO REF+HHO CHIP EFIE:

If you want to double your mileage with HHO gas and HHO chip 3, following the guidelines in this content is essential. Specifically, you should only use 3-7 watts of hho gas and no more, as anything more will only worsen the situation. Additionally, it would help if you tried to keep your speed at around 74-80 km/h like TESLA S to get the most out of your HHO gas. If the range on the dash starts to decrease, we recommend using the new HHO REFtubes and HHO with 12 watts for maximum fuel economy or 22 watts for low smoke, odorless and low emissions. 

  1. Would a larger unit be preferable to a smaller unit? More HHO gas, more fuel-saving?
    Adding more HHO gas can increase the moisture in the exhaust emission recirculation line with the EGR valve and inflate the carbonisation and intake blockage tremendously, especially in EURO 5-6-7 engines, which will cause a reduction in power and an increase in fuel consumption.

    When burning HHO gas, the only byproduct is pure water! If you burn an extreme amount of hho gas there will be a lot of water in the exhaust manifold and corrosion will cause the muffler to be replaced more often.

    Watch video: Is more HHO gas better or not? We did a fuel consumption test.

  2. If you don't have access to an HHO + REF DYNO test, it's still possible to optimize your fuel consumption by driving at the most fuel-efficient speed and using cruise control. Conducting tests at 74 km/h on roads and 100 km/h on motorways can be helpful, especially if your vehicle has a 5-speed automatic transmission.

    When using a VP15, or VP16 device, you can enable all its functions to add power for activities like drifting. However, it's important to note that you might achieve better results without increasing power. When using an HHO chip, it's recommended to adopt a gentler driving style to ensure optimal fuel savings and efficiency.

    In cold weather, when the engine is cold, it may take more time for negative ion tubes to receive infrared radiation from the engine. This is because the engine needs to warm up before it can emit sufficient heat. During this period, the vehicle's performance and efficiency may be temporarily reduced. It's essential to allow the engine to warm up adequately before expecting optimal performance from the negative ion tubes or other components reliant on the engine's heat.

    Let's say you get the best fuel consumption between 94 or 97 km of driving at same speed. HHO works with the HHO chip that searches for the best performance of your engine. Not all gears have the same engine power, and therefore consumption varies. Turn off all electrical appliances and lights and start looking for which watts are more suitable for your economical driving style in the highest gear. The same applies in the city. 47 or 50 km/h.

    Try to drive where it is prescribed (100km) to drive 94 km/h or where it is (80) 74 km/h with HHO CHIP 1, 80-100-120km/h with 5watts basic iX HHO KIT+HHO REF+HHO CHIP. It always works with top gears and the best engine power and torque.

  3. Do not use cruise control in mounting. This function worsens consumption, especially in mountainous terrain.

  4. If you have an automatic gearbox with Tiptronic, always use a higher gear with a minimum speed of around 1200-1350rpm

  5. Always drive, keeping in mind that you have the last litre in the tank and the nearest gas station is 50 km away.

  6. As you drive with more experience, you can achieve your first fuel efficiency record in the best way.

  7. From now on, you'll know what speed and driving style are best to get the maximum benefit from the engine's performance.

  8. New bio components in diesel fuel are worse for engine operation, so we recommend cleaning the injectors once in a while by pouring a special liquid purchased in car parts shop into the tank. They can help restart the functionality of the injectors. 

  9. Whenever the fuel consumption returns to normal, press the reset button in the HHO chip at a temperature of 80°C. I already do it every time I fill up with winter diesel, where there are many bio ingredients from corn and the quality of the fuel dropped rapidly. Diesel is now labeled B5, B7, B12, B15 and the plan is up to B30, which means 30% corn. I recommend using the injector cleaner every three months as per the instructions. This always takes place in states of war as it has been since 1920 throughout Europe.


    Optionally, to boost fuel efficiency, we suggest that customers carry out a more intensive 16-22W engine carbon cleaning for cars during each engine oil change interval. This method can significantly enhance engine performance and fuel economy without the constant use of HHO and longer top-off water intervals.

  11. Basically, in winter conditions, when the fuel is of poorer quality, the fuel efficiency is different than in summer with lower fuel consumption. Also more frequent use of lights, wipers, window heaters, seats, steering wheel increases consumption and it is difficult to solve as the alternator works more and puts a huge strain on a sometimes already old battery with a lack of capacity. This can be easily solved by reducing the speed by 1-5km/hr to get the desired fuel economy.

  12. It is normal for fuel consumption to jump by +1 or +3 litres in winter? Yes. We recommend using heaters as little as possible, reduce speed and accelerating with effective braking, and refuelling with higher octane fuels. The regular octane rating for diesel in Ireland is 51 and Plus 54, and for petrol 95 with Plus 97%. The best is V-POWER SHELL 100 but it is not available in every country.

  13. In case the situation doesn't allow you to drive drastically economically, customers can solve it with an electronic fuel injection called EFIE HHO CHIP 1,2,3 and upgrade fuel quality by HHO REF- FUEL MOLECULES ACELERATOR ALTERNATOR RELIEF Optimization.
