The Enginetech EM4507 exhaust valve features a 1.102" head diameter, 0.2348" stem (6mm nominal), and 4.012" overall length with a chrome-plated stem. Fits 2005-2016 Audi/Volkswagen 1.8L/2.0L/2.5L/3.0L/3.2L applications.
Important Notes
- Sold individually as a single valve. Order the quantity required for your engine configuration (typically one per cylinder per valve position).
- Chrome-plated stem provides a hard, low-friction wear surface for extended service life.
- Always verify head diameter, stem diameter, overall valve length, and groove count against the OE valve being replaced before installation - valve dimensions vary across engine families and a visual match alone is not sufficient.

Enginetech standard valves are stock-replacement engine valves produced from OE grade materials or better, engineered with the production engine rebuilder in mind. Face runout, stem finish, and stem diameter tolerances are held to some of the tightest standards in the internal engine parts industry, and every valve is inspected by on-site engineers against a documented quality plan before it leaves the plant. The line covers domestic, import, and common high-performance applications across a full range of head diameters, stem diameters, and overall lengths, with chrome-plated and nitride-hardened stem finishes available where the engine's operating conditions call for the upgrade. Always verify head diameter, stem diameter, valve length, groove count, and any oversize stem requirement against the original valve being replaced before installing, as multiple valve configurations can share the same vehicle nameplate.
