GSC Power Division Stainless Steel Intake Valves – Audi Daza/DNWA 2.5L 5-Cylinder - GSC2256-10

Boost the performance of your Audi Daza or DNWA 2.5L 5-cylinder turbocharged engine with GSC Power Division’s stainless steel intake valves. These precision-engineered components are designed to enhance airflow, improve efficiency, and withstand the rigors of high-boost applications.

Featuring a back-cut profile, these valves promote smoother intake flow, helping your engine achieve higher RPMs and increased horsepower. The micro-polished stems reduce oil retention and friction, ensuring smoother valve movement and extended durability—even under extreme operating conditions.

Constructed from high-grade 21-4 stainless steel, these valves are built to handle the intense heat and pressure found in forced induction setups. Hardened tips maintain consistent contact with rocker arms, minimizing wear and extending valve life.

Designed as a direct OEM replacement, these valves are compatible with factory keeper/lock systems. For high-performance builds, GSC recommends installing new valve locks to prevent wear-related grooving.
