GSC P-D Subaru FA20F WRX 2015+ 23-8N Chrome Polished Exhaust Valve 30mm Head +1mm - (8)

Engineered for the Subaru FA20F WRX from 2015 onwards, this set of eight GSC Power Division exhaust valves features a 30mm head diameter with a +1mm size increase for enhanced airflow and performance. Crafted from modified 23-8N stainless steel, these valves offer superior heat capacity and durability, ensuring longevity under high-performance conditions.

  • Swirl polished heads for smoother airflow over the valve
  • Back cut design reduces valve weight for higher RPM and boost pressure
  • Micro-polished stems minimize oil retention and reduce drag for smoother valve motion
  • Hardened or stelite wafer fused valve tips for extended life and reduced wear
  • Optimized valve tip lengths for proper valve train geometry and easier valve lash adjustment
  • Adjusted keeper groove balances exhaust spring pressures to reduce shim use and maximize spring kit performance
  • Compatible with OEM or upgraded keeper/locks (replacement recommended for performance use)

These valves are flow tested and designed with advanced 3D simulation to provide the highest flowing valve head available, minimizing valve face distortion for better sealing and consistent performance under extreme conditions. They are an ideal upgrade for sport compact performance enthusiasts seeking reliability and improved engine efficiency.
