If you want to enhance the cooling capacity of your 2011–2014 WRX or STI but you already have a pipe or you need to have custom piping installed, this is the core-only option for you. A by-pass valve with the COBB LF BPV's small size and light weight can withstand very high boost pressure without leaking. With its new design, the control volume is 30% lower, allowing for incredibly quick boost venting when activated. Innovative engineering and careful manufacturing combine to create a small package that can fit into a small engine bay. The LF BPV's moving parts have less inertia and may react more quickly than heavier components in conventional bypass valves because of the components' low weight. This redesigned design makes use of a vacuum port with a Banjo fitting that allows for 360-degree hose routing adjustment. Compared to NPT ports, this results in a simpler installation process and fewer potential leak spots. Additionally, the piston o-ring seal in the new design has an expanded diameter that allows for greater seal compression and less wear. The improved spring and seal design, which offers a 60% increase in clamping force at peak boost while preserving similar behavior at idle and transient loads, eliminates the need for adjustment of the spring seat.
