Ferrea Ford EcoBoost 3.5L 37mm 5.48mm 97.65mm 3.8mm 19 Deg S-Flo Comp Plus Intake Valve - Set of 12

If you're rebuilding the top end of your Ford EcoBoost 3.5L engine, especially if you're looking to improve airflow or are dealing with worn-out original valves, these Ferrea Comp Plus intake valves are a solid choice. They are designed to handle the demands of performance applications and help your engine breathe easier.

These valves feature a 37mm head diameter and a 5.48mm stem, with an overall length of 97.65mm. The 19-degree seat angle is optimized for better flow into the combustion chamber. Ferrea uses high-strength steel for these valves, which is crucial for durability under high temperatures and pressures. The S-Flo design means they have a slightly undercut stem and a swirled head face, which helps improve airflow characteristics compared to standard valves.

This set includes 12 valves, enough for a complete engine rebuild. They are a direct replacement for your stock valves, making installation straightforward if you're already doing a cylinder head job.
