The super, awesome, bad ass (you get the point) COBB XLE BPV for your Subaru WRX 2008-2014 is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking and its unique design allows extremely fast venting of boost when actuated. It is designed to operate in multiple venting modes and can be quickly reconfigured using simple hand tools. Innovative engineering and precision manufacturing result in a compact package able to fit in the confines of a tight engine bay.
The XLE BPV supports three operating modes: full recirculation back into the intake tract, hybrid mode venting to the intake track and atmosphere and full atmospheric with all air vented to atmosphere. The spring preload adjuster allows fine tuning of the pressure required to open the valve. Operating mode and spring preload are both adjustable using simple hand tools.
