Ferrea Nissan SR20DE 31.15mm 5.94mm 102.4mm 22 Deg Flo +1mm Super Alloy Exhaust Valve - Set of 8

These Ferrea exhaust valves are made from a super alloy, a strong material chosen for its ability to handle high temperatures and pressures found in performance SR20DE engines. Each valve measures 31.15mm in diameter, which is 1mm larger than stock, helping to improve airflow out of the cylinder. The 5.94mm stem diameter and 102.4mm overall length are designed to fit SR20DE cylinder heads with minimal modification, and the 22-degree seat angle is standard for many performance applications.

When you're rebuilding the top end of your SR20DE, especially if you're aiming for improved performance, using valves built to withstand the heat and stress is crucial. Ferrea uses advanced metallurgy for these valves, ensuring they resist warping and wear even under demanding conditions. The +1mm oversize design is a common choice for tuners looking to increase exhaust flow without major head work, making them a solid option for a wide range of SR20DE builds.

This set includes eight exhaust valves, enough for a complete engine. Proper installation in the cylinder head is key to their performance and longevity, so be sure to follow the manufacturer's guidelines for seating and valve guide clearance.
