Description

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.
