Audi 4.0T Blow-Off Valve Conversion Kit | Audi 4.0T | TGK Motorsport

Overview

Tired of dealing with boost leaks caused by factory or aftermarket electronic diverter valves? The TGK Motorsport BOV Conversion Kit is the solution you've been looking for. By switching from electronic diverter valves to a mechanical blow-off valve (BOV), you can eliminate the common issues associated with electronic valves.

Our BOV kit uses the factory vacuum and boost reference port to ensure the valve stays fully closed during boost, eliminating any potential for leaks. With no leaks, your engine can perform at its best, and your turbos will run more efficiently. Not only does this upgrade enhance performance, but it also removes the recirculation noise from the diverter valves, allowing you to enjoy the signature sound of a blow-off valve.
