Nitrous oxide carries more oxygen to your 1997 Volkswagen Passat engine in order to allow faster burning of the fuel and to generate more power. During high temperature, such as those found inside a firing cylinder, nitrous oxide breaks down into nitrogen and oxygen gas. Through this, it will raise the pressure of the oxygen in the gas mix above the level present in the atmospheric air and let fuel burn more efficiently. Nitrous system can increase power by up to 45% depending on the configuration and are usually built in one or two stages. To ensure continuous and consistent nitrous injection purge valves are also installed in your Volkswagen Passat. B7080-140743 Bosch purge valve is designed to purge nitrous at the solenoids for efficient nitrous injection. The valves are the ones that eliminate the lag time caused from vapor accumulation in the supply line. The Bosch purge valve creates an instant sledgehammer in your vehicle’s nitrous system. By clearing the tubing of any gaseous nitrous oxide, your nitrous system will therefore provide harder and more stable shot. Want to purchase this product but do not have the time of doing so?
