I got unit working on my
car, my father MPV van, on Brother Benz320L , In Honda Civic which is my younger brother car & some in my friend car.I just a part time hobbyist and last time i sell the unit just to cover my cost of inventing. And I order the titanium & the Nickel Alloy from oversea min order needed so I have to order a lot.The feedback from my Europe customers are great there are about 20~35%fuel economy. Now no time to doing the kit & it simple to duplicate, They just buy some unit from you, then were go on manufacturing themselves. But You can actually feel the car acceleration different between with or without the HHO kit.You can read my blog on may 2010 the full specification on Drycell are showed It simple to duplicate You can DIY yourself.Try to get the 316LSS or you can also use 304SS which is much cheaper but it would not last longer as 316L. If you want the cooler you can get for the Air-con accessories shop it sell as condenser but not so suitable for install in car or you can get from car accessories there sell as oil cooler which also very expensive & aluminum base of oil cooler were erosion by KOH try to get the copper base it corrosive resistant from KOH. At the end of day for the spec. using in my car was custom made from the factory actually I order 50 pcs just to get one for my car. In term of the ignition booster it just the simple capacitor and some diode. If you do no want to DIY, just get the cheaper car VS in market then install in as the diagram direct to the ignition coil i show on previous post rather than install to the car battery.
