Supertech BMW M50/M52 30.5x5.96x105.65mm Black Nitrided Exhaust Valve - Set of 8

These Supertech exhaust valves feature a black nitrided surface treatment, a process that hardens the surface and improves wear resistance. Each valve measures 30.5mm in diameter with a 5.96mm stem and a total length of 105.65mm. This set includes eight valves, designed to replace the stock exhaust valves in BMW M50 and M52 engines.

The black nitriding process not only adds durability but also helps reduce friction, which can contribute to improved valve train stability at higher RPMs. The precise dimensions ensure they are a direct fit for the intended engine applications, making them a solid option for rebuilds or performance upgrades where reliability is key. This well-built component is crucial for proper engine breathing and performance.

When rebuilding an M50 or M52 engine, using valves that can handle the demands of modern fuel and driving conditions is important. These Supertech valves offer a good balance of material strength and surface treatment for longevity and consistent performance.
