Ferrea Nissan SR20DE 31.15mm 5.94mm 102.4mm +1mm Super Alloy Exh Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your Nissan SR20DE engine, especially for a performance build or a refresh, you'll want to make sure your exhaust valves can handle the heat and pressure. This single exhaust valve from Ferrea is made from a super alloy, which is a strong material designed to resist the high temperatures found in the exhaust port. It's a +1mm oversized valve, meaning it's slightly larger than stock, which can help improve airflow into the cylinder.

Ferrea is known for making well-built valvetrain components, and this exhaust valve is no exception. The super alloy construction means it's built to last under demanding conditions. The valve measures 31.15mm in diameter with a 5.94mm stem and a 102.4mm overall length, designed to be a direct replacement for your stock valve, but with improved material properties for better performance and longevity.
