Supertech BMW S14/S38 Black Nitrided Exhaust Valve - +1mm Oversize - Single

Supertech is known for making well-built valvetrain components, and this exhaust valve is a prime example for your BMW S14 or S38 engine. If you're rebuilding the top end or looking to refresh your engine's breathing, this valve is designed to handle the demands of these performance engines.

This is a +1mm oversize exhaust valve, meaning it's slightly larger than stock. This can help improve airflow into the combustion chamber, especially if you're porting or modifying your cylinder head. The black nitriding treatment on the surface adds hardness and improves wear resistance, which is important for an exhaust valve that sees high temperatures and constant motion. It's a single valve, so you'll need to order the correct quantity for your engine's needs.
