TurboXS Blow Off Valve - Type H-RFL (Real Friggin Loud :))
Designed for high performance and maximum sound, the RFL relieves the air pressure surge caused by changing gears or backing off the throttle quickly. The RFL is designed for turbo charged engines running 10 to 25 psi boost. It is an open-loop system, meaning it vents to the atmosphere, and the flared opening produces a strong whooshing sound.
Kit includes : TurboXS Blow Off Valve - Type H-RFL, Mild Steel Zinc Plated Weld-on Adaptor, Aluminum Weld-on Adaptor, Spring Adjusting Packer Washers, and Installation Guide.
