These Ferrea Competition Plus intake valves feature a 2.1-inch face diameter and a 5/16-inch stem, measuring 5.275 inches overall length. The S-Flo design incorporates a unique swirl pattern on the face to improve airflow into the cylinder, especially beneficial for performance builds.

The 12-degree seat angle is a specific design choice that can help optimize valve seating and sealing within certain cylinder head configurations.

Ferrea is known for well-built valvetrain components, and these valves are designed to handle increased stress from higher RPMs and more aggressive camshaft profiles.
