{"product_id":"vag-1-0-tsi-gti-dump-valve-kit","title":"VAG 1.0 TSI\/GTI Dump Valve Kit","description":"The Forge Motorsport Dump Valve Kit (FMDV18) is engineered for VAG 1.0 TSI\/GTI engines, including the VW UP, to enhance performance and sound. As these engines do not come with a standard diverter valve, this kit introduces a twin-piston dump valve that provides a loud, distinctive sound upon throttle lift-off and improves throttle response by reducing turbo lag. This design also aids in maintaining the turbocharger's rotational speed for quicker acceleration and contributes to prolonging the turbo's lifespan.\n\nThe kit addresses the limitations of the OEM boost pipe, which can become brittle and prone to boost leaks due to its exposed position and the engine's heat cycles. The components include anodized CNC-machined billet couplers and a tuneable CNC-machined twin-piston Forge Motorsport valve. Unlike some aftermarket valves, this Forge valve is designed not to trigger check engine lights (EML).\n\nThe product is backed by a limited lifetime warranty, excluding brake pads. Please note that the 2021 and later VAG 1.0 TSI engines may have differences in map sensor and turbocharger coupler, and FMDV18 is not compatible with these specific configurations. The kit includes the atmospheric dump valve, boost tap, throttle body coupler, uprated spring (for mapped engines), hose coupler, blanking plug, silicone hose, clamps, bolts, vacuum tubing, and a wiring loom extension. Comprehensive fitting instructions are provided.\n\nThis dump valve kit is specifically designed for VAG 1.0 TSI\/GTI engines and is not compatible with later 2021+ models of the Seat Ibiza, 2022+ Skoda Fabia, or 2024 Volkswagen Polo 1.0 TSI, which may require the FMDV46. The product is also noted as discontinued, with an estimated restock date of 16\/06\/2026.","brand":"Forge Motorsport","offers":[{"title":"Default Title","offer_id":52688423911736,"sku":"FMDV18","price":347.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664711431.webp?v=1784889966","url":"https:\/\/store.motormia.co\/products\/vag-1-0-tsi-gti-dump-valve-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
