MIA's Description

The Supertech Stainless Steel Black Nitride (BN) Exhaust Valves combine EV8/21-4N stainless steel strength with a low-friction, wear-resistant surface. This construction results in reliable sealing, smoother operation, and a long service life suitable for street performance, track days, and moderate boost applications.

Key benefits include improved wear and corrosion resistance, thanks to the Black Nitride surface treatment that helps reduce friction and scuffing. The hardened tips and controlled stem finish contribute to extending the life of valve guides and followers.
