COBB Tuning LF Bypass Valve

The COBB Tuning LF Bypass Valve is capable of holding very high boost pressures. This is an updated design that reduces the control volume by 30% allowing for extremely fast venting of boost pressure without the risk of leaking. If you have bolt-ons that increase the boost or horsepower, you could surpass the limits of the factory bypass valve which could leak boost and handicap your power potential. The COBB Tuning unit is super durable, with strong internal construction.

The LF Bypass Valve is a direct replacement for the factory bypass valve and has an OEM-like flange for a simple installation.
