Ferrea Ford DURATEC 23E 36.08mm 5.48mm 103.6mm 20 Deg S-Flo +1mm Comp Plus Intake Valve - Set of 8

These Ferrea Comp Plus intake valves are built with a specific 20-degree S-Flo angle and a +1mm oversized head diameter, measuring 36.08mm. This design choice is aimed at improving airflow into the combustion chamber, especially in modified Duratec 23E engines. The overall length of 103.6mm and stem diameter of 5.48mm are engineered to fit specific Ford Duratec applications.

Ferrea uses a well-built steel alloy for these valves, chosen for its ability to withstand the high temperatures and stresses found in performance engine builds. The Comp Plus series often features specialized treatments or designs to handle increased cylinder pressures and higher RPMs. This set includes eight valves, enough for a typical four-cylinder engine rebuild or upgrade.

When rebuilding or upgrading your Ford Duratec 23E engine, using valves designed for improved flow can make a notable difference in performance. Ensure you have the correct valve guides and seals for these specific dimensions to achieve optimal results.
