GSC Power-Division Super Alloy Exhaust Valves for FA20 FRS/BRZ are for those running high-horsepower, high EGT setups that need a valve that will last in 2000°F conditions. The Super Alloy Exhaust valves have chrome polished stems to create a smooth, durable finish for added life and better lubricity, especially when paired with the GSC Manganese bronze valve guides.
Strength, heat resistance, and performance are engineered into every valve. Under-head dish is maximized for weight savings, while swirl-polished and backcut heads promote better air flow without sacrificing durability.
