Supertech BMW M50/M52/S50/S52 Black Nitrided Exhaust Valve - Set of 12

The black nitrided surface on these Supertech exhaust valves is a key detail for BMW M50, M52, S50, and S52 engines. This treatment hardens the valve face and stem, making it more resistant to wear and heat in the combustion chamber. If you're rebuilding the top end of one of these popular BMW inline-six engines, these valves are a solid choice for ensuring reliable performance.

Each valve in this set of 12 is made from high-quality steel, chosen for its ability to withstand the high temperatures and pressures found in performance engines. The nitriding process creates a durable, wear-resistant layer that helps the valves seal better and last longer, especially when compared to standard, untreated valves. This attention to material and surface treatment means you're getting a well-built component that's ready for the demands of your engine build.

When you're putting together a performance engine, the details matter. These Supertech valves are designed to be a direct replacement for your stock exhaust valves, simplifying the installation process. Make sure to check your engine's specific requirements and consult a service manual for proper installation procedures.
