ZRP +1,0mm Exhaust Valves Inconel for Audi VW Volkswagen 2.0L TFSI EA888 EA113

Audi / VW 2.0L TFSI (EA113 / EA888) – ZRP +1.0 Exhaust Inconel Valves (Set of 8)

ZRP +1.0 Exhaust Inconel Valves are engineered for high-performance Audi and Volkswagen 2.0L TFSI engines (EA113 and EA888), where increased exhaust temperatures and elevated cylinder pressures require components with exceptional strength and thermal stability. Manufactured from premium nickel-based superalloys (Inconel 751 / 600 series), these valves deliver reliable performance and long service life in conditions where standard stainless-steel valves are no longer sufficient.

Designed for extreme-duty applications, 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 durability and consistency are critical.

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