Supertech BMW M50 52 31.5x5.96x105.65mm 1+mm Blk Nitride Exhaust Valve - Single (Drop Ship Only)

This Supertech exhaust valve features a black nitride coating, a surface treatment that helps resist wear and improve durability. It's built to the specific dimensions of 31.5mm intake diameter, 5.96mm stem diameter, and a length of 105.65mm, with an additional 1mm oversize to ensure a good seal in your BMW M50 or M52 engine.

The black nitride finish is a practical choice for exhaust valves, as it adds a layer of hardness to the surface. This helps the valve stand up to the high temperatures and stresses it experiences during operation, potentially extending its service life compared to a standard valve. This valve is sold individually, so you'll want to order the correct quantity for your engine's needs.
