The COBB XLE BPV is a compact and lightweight by-pass valve that is capable of holding very high boost pressure without leaking.

Its unique design allows for extremely fast venting of boost when actuated. It is designed to operate in multiple venting modes and can be quickly reconfigured using simple hand tools.

Innovative engineering and precision manufacturing result in a compact package able to fit in the confines of a tight engine bay.

OPERATING MODES

    Full Recirculation - Outlet is plumbed back into the intake tract pre-turbo. This configuration provides the best driveability with stock based MAF systems. This configuration generates the least amount of noise.

    Hybrid Mode - Outlet is plumbed back into the intake tract pre-turbo and the auxiliary port cover is removed. When the piston is more than 30% open, the auxilliary port is opened, audibly venting to atmosphere. Less than 30% opened results in full recirculation to improve driveability.

    Full Atmosphere - Outlet and auxiliary port are open to atmosphere. Recommended only for MAP based air metering. This configuration generates the highest sound levels.

ADJUSTMENT

    Spring Preload - Spring preload determines the pressure differential across the BPV piston required before the BPV opens and releases the pressurized intake charge. The COBB XLE BPV can be adjusted by loosening the locknut and turning the allen-head shaft clockwise for more preload or counter-clockwise for less preload. Once preload is set, the locknut is retightened and ensures the adjustment is secure.

TECH TIP: Direct bolt on, includes all hardware for an easy installation! No other mods or expensive installation kits needed.
