HHO Car Kits

Choose between the HS Pro series and the HSL series. The second one is more budget, cause they are smaller and cheaper. They are divided into three categories: Basic HHO Kit (without PMW’s), HHO Kits with Constant Current PWM, and HHO kits with Dynamic PWM. You will need a control device to control the system properly. For total optimization of the system, choose a Dynamic PWM for Diesel or Petrol injection engines, according to your engine type. If you want a cheaper control device, choose from category HHO kits with CC PWM. All abbreviations of the models are based on the maximum engine displacement, so based on that, you can choose your HHO kit.
