Supertech Nissan SR20DET 31.15x6.94x102.40mm Inconel +1mm Exhaust Valve - Single (Drop Ship Only)

Supertech is well-known for making solid valvetrain components, and this exhaust valve for the Nissan SR20DET is no exception. This is a single exhaust valve designed to be 1mm larger than stock, which can help improve airflow into the cylinder. It's constructed from Inconel, a material that's excellent at handling the extreme heat found in exhaust ports, making it a good choice for performance builds or engines that see a lot of abuse.

When you're rebuilding the top end of an SR20DET, especially if you're aiming for more power or dealing with a high-mileage engine, replacing the valves is a smart move. These valves are built to withstand the demanding environment of the exhaust side. The +1mm sizing is a common upgrade for SR20DETs looking for a bit more performance, and using a heat-resistant material like Inconel ensures they'll hold up under pressure.
