BMW HHO installed on a 2004 325i from a HG S7 HHO Kit from HydrogenGarage.com/store • HHO kits this size start at $495.00 All fitted into the extra battery bay on the passenger side. Gain more HP and save fuel by 25% approx. Clean up your engine from carbon build up, use the cheaper fuel, as the added HHO is like adding 120 octane booster to your ride. We make 90% ortho (-) charged static gas from water, that our (-)H bonds to carbon (+) and blows it all apart in the cylinders resulting in way cleaner emissions better than anything C.A.R.B. can come up with. ALL FACTS. Been making this cell kits for over 12 years. Licensed to sell Bob Boyce™'s 1981 gag ordered patent. A retired DOD scientist. WWG1WGA. SAVINGS on FUEL : Used to get 20 to 22 MPG around town driving, now getting 25 to 26 MPG and more HP. Similar to adding 120 octane fuel booster!! DOD science Hydroxy Gas™ Bob Boyce™ the name of this "ortho" (-) spin state gas all from distilled or filtered R.O. Water. After one month of install, the cell is becoming more efficient as the gold from the ormus in the water starts to form a catalytic layer on the (-) Hydrogen side of the plates. I turned down the duty cycle to 50% now 3.4 to 4 amps us all. When you turn off the HHO, the car seems sluggish, you get used to the extra power. Also am slowly cleaning out all carbon from the engine, my exhaust now idles clean, less carbon smell. You can not hurt the engine, only enhance the combustion with a small amount of 90% (-) charged ORTHO HHO, not common para HHO, like the rest make. It takes a DOD scientist to figure this out.

Also works with Volo Performance VP-16 touch screen (scangauge) VP-15, FS2 and Darol Mason AFR Circuits. MPG results page (since 2007 till 2020)

Home of Hydrogen Trucker as well. We have HHO systems for 15L diesel engines. SAVE on fuel, burn all the fuel you purchase and gain more HP!

We have been making HHO water cells since 2007.
