The GSC Power-Division Super Alloy Exhaust Valves are purpose-built for high-performance FA20 engines operating under extreme EGT (Exhaust Gas Temperatures) — up to 2000°F. Designed specifically for 2013 Subaru BRZ, Scion FR-S, and Toyota 86, these valves are ideal for turbocharged, supercharged, or high-compression NA builds pushing serious power and heat.
Each valve features a super alloy composition, swirl-polished and back-cut head for maximum flow, and chrome-polished stems for reduced friction and longer life — especially when paired with GSC bronze valve guides.
