What is HHO and How Does it Work?

Check out our How Does HHO Work page for information on what HHO is, how it works, and if it is safe!

Is It Hard To Install HHO Systems / Kits?

Nope! Most kits can be installed in a few hours. We give you full detailed instructions so installation should be a breeze.

Does It Work On Diesels And/Or Turbo Chargers?

Yes! The only car we have not been able to install an HHO Kit onto is a Ford Diesel PowerStroke model. The only reason why is because it has a pre-combustion chamber to begin burning fuel before it hits the engine. Any large rig with this (which is uncommon), cannot use the HHO Kit.

We recommend using our search system located on the HHO Kits Home page.

Will An HHO Kit Void My Warranty?

Nope! The conditions that may void a vehicle's warranty are specified in a law called the Moss-Magnusson Act which stipulates dealers cannot void warranties because vehicles have aftermarket parts. An HHO Kit is simply considered an aftermarket kit and can be removed at any time.

Can I Build My Own HHO Generator and Kit?

You can build your own HHO Kit. We do want to warn you that there is a ton of bogus scams out there that claim to give you the world for $60 dollars worth of parts.... Sadly, it just doesn't happen that way. So we have reviewed the top guides to building your own HHO Generator and if you desire to make your own then we highly recommend you check out this review.

Our HHO Kits are a result of over 7 months worth of testing and research and as such you will have a hard time building something superior to our designs unless you put a lot of research into your kit.

Can I Return My HHO Kit?

You have a full 30 days to return your HHO Kit for any reason as long as you have not used it yet. If it is used, sadly we do not accept returns unless there is a malfunction or something is broken upon arrival.

To return you must have a Return authorization number. To get more information about returns please visit our Returns page.

Do You Offer Installation?

No, we do not offer installation of any kits. We recommend talking to a local mechanic to see if they can install it for you if you do not want to install it yourself.

We offer a detailed instruction manual for installing your HHO Kit so you can either use that to do it yourself or show a mechanic.
