ZRP Std Exhaust Valves Inconel for Audi VW Volkswagen 2.0L TFSI EA888 EA113

Audi / VW 2.0L TFSI (EA113 / EA888) – ZRP Standard Exhaust Inconel Valves (Set of 8)

ZRP Standard Exhaust Inconel Valves are designed for high-performance Audi and Volkswagen 2.0L TFSI engines (EA113 and EA888), where extreme exhaust temperatures and elevated cylinder pressures require components of superior strength and durability. Manufactured from premium nickel-based superalloys (Inconel 751 / 600 series), these valves provide consistent performance and long-term reliability in conditions where conventional stainless-steel valves are no longer sufficient.

Engineered for extreme-duty use, ZRP Inconel exhaust valves maintain their structural integrity at exhaust gas temperatures exceeding 800°C. This makes them an ideal solution for turbocharged and supercharged engines, high-boost builds, and endurance racing applications where thermal stability and reliability are critical.

Each valve is precision CNC-machined, swirl-polished, and heat-treated to ensure excellent dimensional accuracy, surface quality, and durability. Strict tolerances for stem straightness, concentricity, and sealing surfaces guarantee reliable combustion sealing and stable valve operation at high RPM.
