GSC2257-10
Regular price £361.00 Save £-361.00GSC Power-Division Audi Daza/DNWA Engine Super Alloy Performance Exhaust Valves, built for superior airflow, efficiency, and durability in turbocharged and naturally aspirated engines.
The back cut design improves airflow, increasing power output and RPM potential. Micro-polished valve stems reduce friction and oil retention, ensuring smoother operation and longer component life, even at high RPMs.
Crafted from super alloy materials, these valves withstand the extreme heat and stress of turbo and supercharged engines. Hardened valve tips ensure extended durability and optimal contact with the rocker or valve tappet.
Designed for OEM replacement, these valves fit seamlessly with OEM keeper/lock systems. GSC Power Division recommends using new valve locks in performance setups to avoid material grooving.

Valve Features:
- Enhanced Engine Efficiency: Improved airflow leads to better engine breathing, resulting in greater power output and overall engine efficiency in both turbocharged and naturally aspirated setups.
- Back Cut Design: Strategically crafted to optimize air flow, allowing your engine to achieve higher RPMs and improved performance across the powerband.
- Micro-Polished Valve Stems: Minimizes oil retention on the valve stem, significantly reducing friction and drag, ensuring smoother motion within the valve guide for improved efficiency and longevity.
- Super Alloy Construction: Designed to withstand extreme temperatures, especially in turbocharged and supercharged engines, ensuring consistent performance and durability under high-stress conditions.
- Hardened Valve Tips: The valve tips are reinforced using a mid-stem friction weld process to extend valve life and minimize wear, ensuring optimal contact with the rocker or valve tappet.
- OEM Keeper/Lock Compatibility: Designed to work seamlessly with OEM triple groove keeper/lock systems. While compatible, we recommend not reusing old valve locks in performance applications to avoid the risk of material grooving.
- GSC Power Division Quality: Backed by GSC Power Division's commitment to delivering top-tier quality and performance, ensuring that every valve meets the highest standards in the industry.
