Supertech BMW M20 37x102.50x6.95mm Black Nitride Exhaust Valve - Single (Drop Ship Only)

The Black Nitride coating on this Supertech exhaust valve is a key detail, offering improved surface hardness and wear resistance compared to standard finishes. This is important for an exhaust valve, which operates under high temperatures and needs to seal effectively against the valve seat for optimal engine performance. This particular valve is sized for BMW M20 engines, measuring 37mm in head diameter and 102.50mm in overall length, with a 6.95mm stem diameter.

When you're rebuilding the top end of your BMW M20, using well-made valves like these from Supertech ensures that each component is up to the task. The Black Nitride treatment not only helps the valve withstand the harsh exhaust environment but also contributes to a smoother surface that can reduce friction. This means the valve can operate more freely, contributing to better engine response and longevity.

This listing is for a single exhaust valve. If you're working on a complete engine rebuild, be sure to order the correct quantity needed for your M20 engine.
