Supertech Nissan SR20D 30.15x5.94x102.40mm Blk Nitride Exhaust Valve - Single (Drop Ship Only)

This is a single Supertech exhaust valve designed for Nissan SR20D engines. It measures 30.15mm in diameter, 5.94mm in stem size, and 102.40mm in overall length. The valve features a black nitride finish, which helps to improve its hardness and wear resistance, making it a solid choice for rebuilding or replacing worn engine components.

The black nitride treatment on this valve is a surface hardening process that also provides a degree of corrosion resistance. This is important for exhaust valves as they operate in a high-heat, high-stress environment within the engine's combustion chamber. Supertech is known for making well-built internal engine components, and this valve is no exception, offering a durable option for your SR20D build.
