High-Temperature Exhaust Valves for Turbocharged G16E-GTS Engines
Boost the performance of your Toyota G16E-GTS with the GSC Power-Division Super Alloy Exhaust Valve Set, engineered for superior airflow, heat resistance, and long-term durability in high-output turbo setups. Each valve features a 32.0mm head diameter and a 117.1mm overall length, making it a direct-fit upgrade for OEM configurations.
Built for Flow, Strength, and Reliability
Constructed from premium super alloy materials, these valves are designed to handle the extreme temperatures and pressures of turbocharged and supercharged engines. The back-cut head improves airflow and RPM potential, while the micro-polished stem minimizes friction and oil retention for smoother operation. Hardened tips ensure consistent contact with the rocker or tappet, even under high stress.
