Supertech Subaru EJ20/EJ25 Black Nitrided Exhaust Valve - Set of 8

Supertech is known for making well-built valvetrain components, and this set of eight black nitrided exhaust valves is a prime example for Subaru EJ20 and EJ25 engines. If you're rebuilding the top end of your Subaru, these valves are designed to handle the heat and stress of performance applications.

The black nitriding process hardens the surface of the valve, making it more resistant to wear and corrosion. This treatment also helps improve the valve's ability to withstand high temperatures, which is crucial for exhaust valves that deal with the hottest gases in the engine. These valves are a solid option for anyone looking to replace worn-out stock valves or upgrade their engine's valvetrain for improved reliability under demanding conditions.
