2TR Inconel Exhaust Valve
Maximize the high-temperature performance and airflow of your 2TR-FE engine with our +1mm Oversized Inconel Exhaust Valves. Measuring at 32.50mm (1mm larger than the 31.50mm factory standard), these valves are specifically engineered for ported street heads and high-output applications where heat management is critical.
Unlike standard steel valves, these are crafted from a specialized high nickel-based Inconel alloy. Through a unique heat-treatment process, these valves achiever extreme thermal resistance and enormous tensile strength, ensuring superior valvetrain stability under the most demanding conditions.
Why Choose Inconel?
Inconel is the industry standard for high-performance exhaust components because it remains stronger and more durable at extreme temperatures. A cooler-running valve allows tuners more flexibility with spark timing advances and provides a wider safety margin. Combined with an average 10% weight reduction over stock, these are the most advanced valves available for your build.
Features
- Increased Airflow: +1mm diameter 32.50mm for significantly improved exhaust scavenging.
- Superior Materials: Constructed from temperature-resistant Inconel alloy for unmatched durability.
- Swirl-Polished: Finished to a high luster to maximize airflow and minimize carbon buildup.
- Lightweight Design: 10% Lighter than factory steel valves, reducing valvetrain inertia.
- Enhanced Longevity: Hardened tips ensure a long service life even in high-lift applications.
- Compatibility: Designed to work with factory valve guides and seals.
Installation Notes
These valves are compatible with stock seats once a performance valve job has been performed. To fully realize the gains of oversized valves, it is highly recommended to unshroud the valve through bowl and chamber port work.
