Supertech BMW M50/M52/S50/S52 Black Nitrided Exhaust Valve - +1mm Oversize - Single

This Supertech exhaust valve is treated with a black nitride finish, a process that hardens the surface and improves its resistance to wear and corrosion. It's designed as a +1mm oversize replacement, meaning it's slightly larger than the stock valve. This can be beneficial when rebuilding or modifying an engine, especially if the valve seats have been reconditioned or if you're looking for a bit more flow potential.

The valve itself is built for performance applications, often used in BMW M50, M52, S50, and S52 engines. The black nitride treatment not only adds durability but also helps the valve perform reliably under the high temperatures and pressures found in the exhaust port. This single valve is a direct replacement for one exhaust valve in your engine.
