Atmospheric Blow Off Valve Aluminium for Volkswagen GTi Golf Jetta A3 A4 A6 TT
Upgrade your turbo setup with this Atmospheric Blow Off Valve in aluminium, designed for Volkswagen and Audi 1.8T engines. Crafted from aircraft-grade 6061 aluminium, it delivers a precise, rapid release of boosted air after throttle lift. The dual-piston design provides a crisp, controlled venting action that helps prevent compressor surge while enhancing throttle response and the characteristic turbo flutter you expect from a performance build. Compatible with VW GTi, Golf, Jetta, Beetle, A3, A4, A6, and TT models powered by the 1.8T engine, it can also service 2.7L bi-turbo applications (requires two BOV units). The 25mm inlet matches common performance piping for a straightforward upgrade.
Built for durability and reliable ECU interaction, the BOV uses a hard spring to support 1.8T ECU compatibility and consistent actuation. It’s designed for 25mm OD connections, making it a practical upgrade for street or track-ready Volkswagens and Audis. Please note that professional installation is highly recommended, and no installation instructions are included with the kit.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
