Upgrade your Toyota G16E-GTS 3-Cylinder Engine with GSC Power Division Stainless Steel Performance Intake Valves, engineered for superior airflow, efficiency, and durability for turbocharged engines.

The back cut design improves airflow, enhancing power output and RPM potential. Micro-polished valve stems reduce friction and oil retention, ensuring smoother valve operation and extended component life, even at high RPMs.

Made from 21-4 Stainless Steel, these valves withstand the intense heat and stress of forced induction engines. The hardened valve tips offer extended durability, maintaining optimal contact with the rocker arms.

Designed for direct OEM replacement, these valves seamlessly fit OEM keeper/lock systems. For maximum reliability, GSC Power Division recommends new valve locks in high-performance setups to prevent material grooving.

Intake Valves

GSC Power-Division performance valves are designed for high-output engines where material strength, precision manufacturing, and thermal durability directly impact reliability and performance. Produced from carefully selected premium stainless steel and superalloy materials, GSC valves are built to withstand the elevated temperatures, cylinder pressures, RPM levels, and combustion demands found in modern performance engines.

Every valve is manufactured to stringent dimensional and material standards to deliver precise fitment, consistent sealing performance, and long service life. Whether supporting naturally aspirated builds, high-boost turbo systems, endurance applications, or extreme horsepower race programs, GSC valves are engineered to handle conditions where lesser components reach their limits.

Frequently Asked Questions

What materials are GSC valves made from?
