The COBB XLE BPV is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking. Its unique design allows for extremely fast venting of boost when actuated. Innovative engineering and precision manufacturing result in a compact package able to fit in the confines of a tight engine bay. The XLE BPV is able to vent pressurized air more quickly than other bypass valves due to several unique design elements. Due to the low weight of the components, the moving parts in the XLE BPV have less inertia and can respond faster than heavier components in other bypass valves. Furthermore, the shapes of the exhaust port and piston face are designed to evacuate air as quickly as possible. The third design element is treatment of the piston with hard anodizing and a Teflon coating that provides low sliding friction, reduces surface wear and minimizes maintenance requirements.
A compact and very lightweight bypass valve that is loaded with features, has spring pre-load adjustability, and reliably holds high levels of boost without leaks. Use this bypass valve with the COBB 2008-2014 STI FMIC Kit or other custom intercooler kits that utilize a 1" bypass valve inlet.
