GSC Intake Valve Set – Standard Size for Mitsubishi Evo X 4B11T – GSC2022-8

The GSC2022-8 standard intake valve set is designed for Mitsubishi Evo X 4B11T engines demanding high performance and long-term reliability. With a 35mm head diameter and sold as a complete set of 8, these valves are engineered for high boost, high RPM, and aggressive cam profiles.

Specs:

  • Head Diameter: 35.00mm
  • Stem Diameter: 5.5mm
  • Overall Length: 113.15mm

GSC Power-Division developed this valve line using advanced 3D modeling and simulation software to create a stronger, more efficient valve head. Each prototype is flow-tested in its intended application to ensure optimal airflow and minimal distortion. The result: better sealing under extreme conditions and consistent performance throughout the valve’s lifespan.

Key Features:

  • Swirl-polished heads improve airflow across the valve surface
  • Back-cut design reduces weight for higher RPM and boost, supporting aggressive cam profiles without increasing spring seat pressure
  • Micro-polished stems reduce oil retention and drag for smoother valve movement
  • Intake valves use modified 21-4n stainless steel for high heat resistance and long-term durability
  • Valve tips are either hardened or fused with a stelite wafer, maintaining wear resistance within 5 Rockwell C of the rocker or tappet
  • Tip heights are precision-adjusted to reduce install time and maintain proper valvetrain geometry
  • Keeper grooves are optimized to balance spring pressures and reduce the need for shims when paired with GSC spring and retainer kits
  • Compatible with OEM keepers/locks or GSC’s upgraded versions (recommended not to reuse locks in performance builds due to material wear)
