Supertech Inconel Exhaust Valves for Subaru EJ20/EJ25, +1mm Oversize, Set of 8 (SEVI-1014-8)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits Subaru EJ20 and EJ25 engines. These Supertech Inconel exhaust valves are engineered to withstand the extreme thermal loads found in high-boost and competition Subaru boxer engines. Manufactured from a specialized nickel-based superalloy, Inconel provides superior resistance to heat-induced fatigue and oxidation compared to standard stainless steel components.
This set of eight +1mm oversize valves increases the effective valve head diameter to improve exhaust flow and cylinder scavenging, making them an essential upgrade for built cylinder heads targeting higher horsepower. Because these are oversize components, professional machining of the valve seats is required for installation. Each valve is precision-ground to ensure tight tolerances and consistent seating under high-stress conditions.
- Material: High-strength Inconel superalloy
- Valve Type: Exhaust
- Head Diameter: +1.00mm Oversize
- Quantity: Set of 8 valves
- Manufacturer Part Number: SEVI-1014-8
