Supertech Mini Cooper S R53 1.6L Black Nitrided Flat Head Exhaust Valve - Set of 8

If you're rebuilding the top end of your Mini Cooper S R53 with the 1.6L engine, a fresh set of exhaust valves is a smart move. These Supertech valves are designed to handle the heat and stress of the exhaust cycle, helping to ensure your engine breathes efficiently. They are a direct replacement for your stock valves, making them a straightforward part of a larger engine project.

What sets these valves apart is the black nitriding treatment on the surface. This process hardens the metal and creates a durable layer that resists wear and helps to prevent sticking in the valve guides. The flat head design is a standard configuration that works well with most stock and performance camshafts. This set includes all eight exhaust valves you'll need for your engine.
