Ferrea Nissan SR20DET 35.15mm 5.96mm 20 Deg S-Flo Rad Grv +1mm Comp Plus Int Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and this set of eight +1mm Comp Plus intake valves for the Nissan SR20DET engine is a prime example. These valves are designed to handle the demands of a performance-built SR20DET, offering improved flow and durability over stock.

Each valve features a 35.15mm S-Flo radial groove head, which helps improve airflow into the combustion chamber. The 5.96mm stem diameter is standard for many performance applications, and the +1mm sizing means these valves have a slightly larger head diameter than stock, allowing for better cylinder filling. The Comp Plus design is built for engines that see higher cylinder pressures and temperatures, offering a well-built option for serious builds.

When rebuilding or upgrading your SR20DET's top end, using quality valves like these from Ferrea is crucial for reliable performance. Ensure you have the correct valve springs and retainers to match the increased valve lift and flow characteristics.
