COBB Tuning LF Bypass Valve

COBB Tuning LF Bypass Valve

Highlights

• Updated design reduces control volume by 30% allowing for extremely fast venting of boost when actuated
• Compact design allows fitment in a confined engine compartment
• Lightweight components create less inertia and can respond faster than heavier components
• Uses banjo-fitting vacuum port which provides 360-degree adjustability of hose routing
• Piston O-ring seal is twice the diameter of the old design allowing more seal compression and reduced wear
• The adjustability of the spring seat is no longer needed 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

Dont Let Your Boost Leak

This is a compact and lightweight by-pass valve that has been designed to hold high boost pressure without leaking. This is a great option for those with stock or heavily modified vehicles and wants a by-pass valve to be the last by-pass valve you will need.

Easy Installation for Big Street Cred

The C.A.R.B. Certified 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 the old design allowing more seal compression and reduced wear. Adjustability of the 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.
