Complete 2JZ Intake Valve Set

Ensure your 2JZ cylinder head is balanced and ready for high-performance output with this complete 12-piece set of GSC Power Division 21-4N Intake Valves. Specifically designed for the 2JZ-GTE and 2JZ-GE engines, these valves offer the perfect combination of heat dissipation and strength. By replacing your entire intake valvetrain, you ensure consistent performance and prevent the common failures associated with aging factory valves.

Why Choose GSC Intake Valves?

  • Complete Set: Includes 12 intake valves for a full head refresh
  • Material: 21-4N Stainless Steel for extreme heat tolerance
  • Design: Chrome polished for reduced drag and improved flow
  • Fitment: Precision-machined 33.6mm STD head diameter

These valves are essential for builders pushing increased boost levels or higher RPM ranges. The 21-4N alloy is specifically chosen for its ability to maintain structural integrity at elevated temperatures, preventing the valve stretching or burning often seen in stock components. With a polished finish, these valves minimize surface friction, allowing for better intake charge velocity. Whether you are building a street machine or a dedicated track car, this set provides the reliability required for your 2JZ project. GGCRACING carries the full line of GSC valvetrain components to keep your engine running strong.
