Universal Adjustable Recirculating Dump Valve Turbo Blow Off Splitter for 1.8T 2.7L Engines

Introducing our brand new BOV1022 Blow Off Valve, crafted from silver-colored aluminum. This versatile performance part is specifically designed to fit 1.8T and 2.7L turbocharged engines (the latter requiring two valves per vehicle). It is also compatible with any other vehicle with 25 mm (1 inch) inner and outer diameter fittings.

Its key feature is its precise hybrid valve design, which simultaneously combines blow-off and recirculation functions. It is ideal for turbocharged engines using metered intake management systems. Enjoy the characteristic blow-off sound while maintaining compatibility with the engine management system's recirculation requirements.

This valve offers complete flexibility with three possible configurations:

1. Hybrid Mode: Simultaneously operates in atmospheric AND recirculation mode.

2. 100% Recirculation Mode.

3. 100% Atmospheric Mode.

You can fine-tune it to perfectly suit your engine's needs. Precise adjustment is made via the ratchet knob located on top of the valve: turn it clockwise to stiffen the spring and retain more boost pressure, or counterclockwise to loosen the spring tension.

Furthermore, it can be converted to fully recirculated mode for a more discreet approach. Your order includes: 1 x Blow Off Valve, 1 x Vacuum Hose, 1 x Complete Recirculation Plug, 1 x Inlet Pipe Plug, 1 x O-Ring
