About this part

Product Details

Supertech is known for making well-built valvetrain components for performance applications. This set of eight exhaust valves is specifically made for Subaru EJ25 Turbo DOHC engines. They are a +0.5mm oversized option, measuring 104.2mm in length, which can be helpful when rebuilding or upgrading the top end of your engine.

These valves feature a Black Nitride finish. This treatment helps to improve surface hardness and reduce friction, which is important for consistent performance and durability under the heat and stress of turbocharging. The +0.5mm oversize is a common choice for engine builders looking to restore or improve sealing in worn valve seats or to optimize flow in a performance build.

This set includes all eight exhaust valves needed for a complete engine. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
