Supertech BMW M20 Black Nitrided Exhaust Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your BMW M20 engine, getting the right valves is crucial for performance and longevity. This Supertech exhaust valve is made to replace the stock unit, helping to ensure your engine breathes properly under load. It's a single valve, so you'll need to order the correct quantity for your specific engine build.

This particular valve features a black nitrided surface treatment. This process hardens the surface and improves its resistance to wear and corrosion, which is important for an exhaust valve that sees high temperatures and exhaust gas flow. The valve is well-built and designed to fit right into the M20 cylinder head, making installation straightforward when you're doing a full engine overhaul.
