At LowPricedAutoParts – the retailer of automotive parts and accessories that puts an emphasis on customer service – we provide this durable Enginetech exhaust valve (EM4443) for 2005-2017 models with 2.0L TFSI turbo engines, including Audi A4, A3, VW Jetta, GTI, Passat and select higher-displacement 3.0L, 4.2L, 5.2L applications in A6, A8, Q7, R8, S5, S6, S8.
These TFSI turbo engines deliver impressive power and efficiency in premium sedans, hatches and SUVs. A failing exhaust valve can cause low compression, boost leaks, misfires or emissions issues – typical in boosted, high-mileage vehicles.
This single valve features chrome-plated stem (0.2345" diameter) for minimized wear and improved guide compatibility, 1.100" head diameter for effective sealing, 4.013" length and 3-groove design for reliable keeper fit.
Installation notes: Inspect guides/seats (turbo heat is tough on them), lap for perfect contact, set proper lash, use new keepers/springs if needed and test compression/leakdown after reassembly. VIN check is crucial for fit.
LowPricedAutoParts is dedicated to you – send your vehicle info (VIN preferred) for quick confirmation and support. Shop confidently for quality parts and exceptional service. Reach out anytime!
