ZRP Std Exhaust Valves Inconel for Audi VW Volkswagen 1.4L TFSI EA211

Audi / VW 1.4L TFSI (EA211) – ZRP Standard Exhaust Inconel Valves (Set of 8)

ZRP Standard Exhaust Inconel Valves are engineered for Audi and Volkswagen 1.4L TFSI (EA211) engines operating under extreme exhaust temperatures and elevated cylinder pressures. Manufactured from premium nickel-based superalloys (Inconel 751 / 600 series), these valves provide exceptional strength, thermal stability, and long-term reliability where conventional 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, as well as endurance racing and high-output street performance builds.

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