Product Description

The **GSC Power Division 2256-10 Intake Valve Set** is designed exclusively for Audi DAZA / DNWA 2.5L 5-cylinder turbo engines. Each valve is manufactured to OEM-equivalent dimensions (33.9 mm head, 104 mm length) to ensure compatibility and reliability in high-performance or forced induction applications.

Constructed from stainless steel with a chrome-polished finish, these valves resist corrosion and perform reliably under high thermal stress. The back-cut head design enhances airflow efficiency, and micro-polished stems reduce friction in valve guides - improving longevity and responsiveness in the valvetrain.

This set is ideal for performance engine builds or rebuilds where the intake side needs replacement or upgrade. It supports compatibility with upgraded springs, retainers, and high-RPM operation. Always verify compatibility with your specific DAZA / DNWA engine variant before purchase, and consider using new valve locks for optimal durability.
