Forge Blow-off valve, DV (Ford Focus RS 2.5, Chevy Cobalt..)

Piston-Style Bypass Valve for OEM Applications

This piston-style bypass valve is a direct replacement for the factory-fitted valve. Unlike the diaphragm-style (OEM) valves, this piston valve provides enhanced durability and longevity. It’s designed to accommodate different springs, making it ideal for vehicles with increased boost pressure or engine modifications. The valve also features an angled top or vacuum connection for easier installation.

This valve is compatible with K04 turbochargers, offering flexibility for a wide range of performance setups.

Please note, in MAF (air mass sensor) controlled engines, atmospheric blow-off can sometimes need a small adjustment in the tune to avoid fault codes.
