Made from billet aluminum, this recirculating bypass valve dumps the boosted air back into the intake system pro-turbo keeping external noise to a minimum.
Because this valve recirculates the air back into the system, it prevents the valve from causing the driveability issues associated with single piston blow off valves when used on vehicles equipped with an air meter (VAM or MAF).
6mm ID hose fits barely but certainly needs clamped on to prevent it from popping off. 4mm ID hose is tight/stretches over and would not need a clamp. So measure the port you plan to connect it to on the vacuum tree or turbo outlet and measure ports you may also connect to the same hose (like a boost controller) to determine which size you'd rather use so you don't have to adapt to different sizes.
-Designed to be clamped to a 1" hose connection which is available on all of our intercooler kits.
-Works with our Silicone Tee if welding isn't available.
Blow off valve, Replacement preload spring. 1" Silicone Hose for attachment to 1" weld on bung or Silicone Tee available in related items below.
Vacuum port connects to a source that sees both vacuum and boost under each condition which means the signal needs to come from after the throttle body such as connecting directly to the vacuum tree.
