GSC Power-Division STD Intake Valves – Set of 12 (Toyota Supra / BMW B58 & S58) – GSC2092-12
The GSC2092-12 Standard Intake Valve Set is engineered for high-performance builds using Toyota and BMW platforms equipped with B58 and S58 engines. Each valve features a 30.10mm head and is crafted from modified 21-4n stainless steel for strength, flow, and long-term durability under extreme conditions.
Valve Dimensions:
- Head Diameter: 30.1mm
- Stem Diameter: 5mm
- Overall Length: 99.55mm
Developed using advanced 3D modeling and simulation tools, GSC’s intake valves deliver improved airflow and reduced face distortion—resulting in better sealing and consistent performance throughout the life of the valve. Each prototype is flow-tested in its intended application to ensure maximum efficiency.
Key Features:
- Swirl-polished heads promote smoother airflow
- Backcut design reduces valve weight for higher RPM and boost tolerance
- Micro-polished stems minimize oil retention and reduce drag for smoother movement
- Hardened or stelite-tipped ends for extended wear resistance
- Optimized tip height for proper valvetrain geometry and faster lash setup
- Keeper groove adjusted to balance spring pressures and reduce need for shims
- Compatible with OEM or upgraded keeper/lock systems (reuse not recommended for high-performance builds)
Whether you're chasing RPM, boost, or long-term reliability, GSC’s stainless intake valves are built to outperform factory components in demanding environments.
