REGARDING YOUR QUESTIONS:

You will get a faster response via email as we have a large volume of calls and can not always respond to general questions about HHO technology. If you have questions about the HHO kits in general, I recommend you download my FREE course which is a great primer on the technology and should answer most of your general questions. Our HHO generators are built to work with a large variety of vehicles and are not designed for one specific model or car.

Please do not ask if our units will fit in your particular vehicle, as this is impossible to determine. We recommend you review the sizes and dimensions of our generators to decide if they will fit in your car, truck or van, prior to ordering. General questions about the process will most likely not be answered via phone.

If you are unhappy in any way with your purchase or our service, please give us the chance to make it right. You can contact us using the form above. Please review our refund/warranty/replacement policies by clicking on the link.
