Cobb Universal LF BPV

The Cobb Universal LF Bypass Valve (MPN 715665) is a compact, lightweight bypass valve capable of holding very high boost pressure without leaking. Its updated design reduces control volume by 30% for extremely fast venting. Lightweight components ensure quicker response times. Features a 360-degree adjustable banjo-fitting vacuum port for simplified installation and reduced leak points. The piston o-ring seal is twice the diameter of previous designs, enhancing seal compression and reducing wear. An improved spring and seal design provides a 60% increase in clamping force at peak boost while maintaining consistent operation at idle and transient loads. While originally designed for the COBB 715500 Front Mount Intercooler Kit for the 2008-2014 Subaru STI, it is universally applicable for systems requiring a 1" bypass valve inlet.
