This valve is durable and designed to hold more boost without leakage (and also looks much better than the factory valve).
Very high flow rate to properly protect the turbo (even at VERY high boost levels)
Comes with additional springs to adapt to boost level, and shim to fine tune (if desired); also included are new clamps and vacuum hose for plug-and-play installation.
These are also great for custom turbo builds that require a recirculated bypass system, or you can use this as a blow-off valve!
