Forge Motorsport Blow Off Valve Kit for VW 1.0 TSI | Improves Throttle Response

The Forge Motorsport Blow Off Valve Kit is a premium performance upgrade designed specifically for the VW 1.0L TSI engine. Since this engine does not come with a factory diverter valve, Forge developed a fast-response twin piston atmospheric dump valve that delivers an aggressive blow-off sound while reducing turbo lag during gear changes. This helps the turbo maintain rotational speed, improving throttle response and acceleration.

The kit replaces the OEM plastic boost pipe—known to become brittle over time—with a high-quality Fluorosilicone-lined silicone hose available in multiple colors. All components, including CNC-machined billet couplers and a tunable twin piston valve, are engineered to handle high boost pressure without causing engine check lights (EML). With full installation instructions and all required hardware included, this kit is a complete plug-and-play performance upgrade.
