Measuring 30.0mm, these valves are designed to increase exhaust flow, allowing your engine to breathe more efficiently under high-boost conditions. Crafted from premium super alloy, they are engineered to handle the extreme thermal loads found in high-horsepower racing applications, preventing the warping and failure common with stock components.

Technical Advantages

• Increased Diameter: 30.0mm (+1mm over stock) for improved flow dynamics.
• Super Alloy Material: Enhanced heat resistance for sustained high-RPM performance.
• Chrome Polished: Reduces surface friction for faster port velocity.
• Engineered for 2JZ: Compatible with 2JZ-GE and 2JZ-GTE platforms, including Supra and Lexus models.

These valves are an essential upgrade for any serious engine build, particularly when paired with aggressive camshaft profiles and ported cylinder heads. By increasing the exhaust port capacity, you can achieve better scavenging and higher power output. The set of 12 ensures your entire valvetrain is upgraded to the same high standard of performance and reliability.
