VW/Audi Performance Parts: Forge Blow Off Valve Kit for VAG 1.4 TSI Twincharged (FMDVATSI)


Product Features & Benefits

This valve kit is for VAG vehicles equipped with the 1.4 Tsi twincharged (supercharged and turbocharged) engines that have the electronically controlled bypass valves (2 bolt fitting). It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures of the OEM valve, that have occurred.

Forge offers this alternative; a fully engineered solution offering both significantly improved reliability. This valve and installation kit replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. This product has been thoroughly designed and tested with the expressed intent of offering improved valve response and maintaining ECU control while resulting in absolutely NO fault codes, NO check engine lights, and no adverse effects of any kind. All of the necessary components and detailed instructions are included and everything is designed to make installation as simple as possible.
