ProCharger ProRace Blow-Off Valve with 4-Inch Aluminum Tube - Red - 3FASS-018
The ProCharger 3FASS-018 ProRace Blow-Off Valve is engineered for extreme horsepower centrifugal supercharger combinations where maximum airflow and rapid boost relief are essential. Featuring ProCharger's premium ProRace open atmospheric blow-off valve and a 4-inch aluminum mounting tube, this kit is designed specifically for custom intercooler piping built with 4-inch aluminum charge tubing.
During aggressive throttle transitions, the ProRace Valve rapidly vents excess boost pressure to help reduce compressor surge and protect critical forced induction components, including the supercharger, intercooler, and charge piping. The included 4-inch aluminum tube simplifies fabrication while providing a clean, professional installation for custom high-performance applications.
Finished in ProCharger's signature red anodized finish, the 3FASS-018 delivers race-proven performance with an aggressive appearance that looks right at home in serious street, strip, and competition builds.

Built for Serious Boost Levels
As horsepower and airflow increase, proper boost management becomes even more important. The ProCharger ProRace Valve is engineered to respond quickly during throttle lift, venting excess pressure before compressor surge can occur. This helps improve the longevity of expensive forced induction components while maintaining consistent performance under demanding driving and racing conditions.
The included 4-inch aluminum tube makes the 3FASS-018 an excellent solution for builders fabricating custom aluminum charge piping while maintaining the quality, fit, and performance expected from genuine ProCharger components.
