The Comp Plus series valves are constructed from high-strength, heat-resistant materials to withstand the demanding conditions of high-performance engines. Ferrea uses advanced manufacturing techniques to ensure precise dimensions and a smooth surface finish, which helps reduce friction and improve sealing. The undercut stem design is a notable feature that further reduces weight and improves airflow around the valve head, contributing to better engine breathing and performance. These valves are intended for builds where reliability and durability under stress are paramount.

When rebuilding or modifying your RB26, using high-quality valves like these Ferrea Comp Plus units is crucial for achieving optimal performance and longevity. Ensure you have the correct valve springs and retainers that match the valve's specifications and your engine's intended operating range. Proper installation and setup are key to realizing the full benefit of these components.
