Please use this thread for hydrogen boosters for cars. Tube or plate setups welcome. There are plenty of companies selling kits and I can't say who has the best. They are basically mini "Brown's Gas" generators which supplement the fuel/air for more power, less emissions and cleaner engine. But make sure you can manipulate the o2 sensor voltage so it doesn't sabotage your gains from the booster. I'll post more stuff here later and welcome anything anyone wants to contribute.
