Benefits:
- Keep your vehicle's boost from leaking at higher pressure.
- Faster boost venting reduces strain on your engine increasing longevity.
Features:
- Compatible with COBB 2008-2014 STI FMIC or other 1" BPV connections
- 14% Increase in piston diameter over previous version for better response
- 100% Rebuildable if there ever is an o-ring failure
- 100% Billet Aluminum Construction
- 100% O-Ring Sealing
Applications:
- Universal
Application Notes:
- Emissions: This part is legal under the provisions of EPA’s Anti-Tampering Policy. COBB Tuning has established a reasonable basis (testing results) to verify that this product allows the vehicle to operate within legal Emissions: standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and EPA’s Anti-Tampering Policy. NOT LEGAL FOR SALE OR USE IN CALIFORNIA ON ANY EMISSION CONTROLLED MOTOR VEHICLE. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending. Once testing is complete with California, and an EO number is issued, this product will be updated to 50-state legal status.
Description:
This is a "Universal" style valve designed to be used with our COBB 715500 Front Mount Intercooler Kit for the 2008-2014 Subaru STI or other custom configurations that call for a 1" bypass valve inlet.
For a direct bolt-on Bypass Valve, visit the Blow Off Valves section of our website and ensure your car is configured.
The COBB LF BPV is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking. Its updated design reduces control volume by 30% allowing 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. Due to the low weight of the components, the moving parts in the LF BPV have less inertia and can respond faster than heavier components in other bypass valves. This updated design uses a Banjo-fitting vacuum port which provides 360 degree adjustability of hose routing. This results in a simpler install and less potential leak points than the NPT ports. This new design also includes a piston o-ring seal that is twice the diameter of old design allowing more seal compression and reduced wear. Adjustability of spring seat is no longer needed due to the updated spring and seal design which provides a 60% increase in clamping force at peak boost while maintaining similar operation at idle and transient loads
A compact and very lightweight bypass valve that is loaded with features and reliably holds high levels of boost without leaks.
