GSC Power Division FA20 Exhaust Valve 29mm Standard Head - Single
This GSC Power Division exhaust valve is engineered for the Subaru/Scion BRZ and FR-S with the FA20 engine. Featuring a 29mm standard head diameter, it is designed to optimize exhaust flow and durability under high-performance conditions. The valve is crafted from a modified 23-8N stainless steel material, providing high heat capacity and longevity. Its swirl polished head enhances airflow, while the back cut reduces valve weight, allowing for higher RPM and boost pressures without increasing valve spring seat pressures. The micro-polished stem reduces oil retention for smoother valve motion and less drag. Valve tips are hardened or feature a stelite wafer tip for extended life and reduced wear. This single valve is ideal for performance upgrades and engine rebuilds.
