Blow Off Valve Kit for Audi A1 A3 Q5 1.8T/2.0T Aluminum CNC Billet High Performance

Upgrade your Audi turbo system with a precision CNC billet aluminum Blow Off Valve Kit designed for Audi A1, A3, and Q5 1.8T/2.0T engines. Crafted with durable surface treatment, this BOV kit brings a reliable, performance-focused solution to turbocharged driving. It’s built to endure high-boost conditions while delivering a responsive throttle feel and a distinctive sound that performance enthusiasts love.

The Blow Off Adapter sits between the existing solenoid valve and the turbocharger housing. By interrupting the recirculation of hot air, it helps reduce turbo lag and improve throttle response, so you notice quicker boost recovery after shifts or abrupt throttle changes. This atmospheric diverter discharges pressurized air into the atmosphere, producing a crisp “swish” sound when you lift off the throttle—an audible cue that your turbo system is working hard.

Designed for OEM valve compatibility and engineered for high-performance turbocharged engines, this kit is ideal for Audi A3 1.4T/2.0T FSI B7 applications as well as the Audi A1, A3, and Q5 1.8T/2.0T variants. The kit includes the essential O-ring and mounting bolt for secure installation. Note that installation instructions are not provided, and professional installation is strongly recommended to ensure optimal fit and function.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
