Supertech Peugeot 306 (XU10J4RS) Black Nitrided Exhaust Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your Peugeot 306 with the XU10J4RS engine, you'll want to make sure your exhaust valves can handle the heat and pressure. This single exhaust valve from Supertech is made from strong steel and features a black nitrided surface treatment. This process hardens the surface, making it more resistant to wear and corrosion, which is crucial for exhaust valves that operate under high temperatures.

The black nitriding not only improves the valve's durability but also helps it maintain a good seal within the valve guide. This is a direct replacement part, meaning it's designed to fit right into your existing valve train setup without modification. It's a well-built component that contributes to the overall health and performance of your engine's cylinder head.
