The GSC Power-Division Super Alloy Exhaust Valves are built for high-horsepower FA20 engines where durability and heat resistance are critical. Specifically designed for the 2013 Subaru BRZ and Scion FRS, these valves are capable of withstanding exhaust gas temperatures up to 2000°F, making them ideal for turbocharged, supercharged, or aggressively tuned naturally aspirated builds.

These valves feature chrome-polished stems for improved lubricity and wear resistance, especially when paired with GSC Manganese bronze valve guides. The under-head dish design reduces weight, while swirl-polished and backcut heads enhance airflow for improved performance without compromising reliability.
