COBB Tuning LF Bypass Valve. 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.
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
