Supertech BMW S14 Black Nitrided Exhaust Valve - Set of 8

If you're rebuilding the top end of your BMW S14 engine, these Supertech black nitrided exhaust valves are a solid option. This set includes eight valves, enough to replace all the exhaust valves in your S14, which is known for its high-revving nature and performance focus.

These valves are treated with a black nitriding process. This surface hardening technique makes the valve face more durable and resistant to wear, which is important for handling the heat and stress inside the combustion chamber. The material itself is well-built to withstand the demanding environment of an exhaust valve, helping to ensure consistent sealing and performance over time. They are designed to fit right into the stock valve guides and seats, making installation straightforward for a rebuild.

When you're putting your S14 engine back together, using reliable components like these nitrided valves can make a real difference in the longevity and performance of your rebuild.
