Ferrea Honda F20C/F22C 37mm 5.48mm 109.8mm 20 Deg S-Flo +1mm Comp Plus Intake Valve - Set of 8

These Ferrea Comp Plus intake valves are built with a specific 37mm head diameter and a 5.48mm stem, measuring 109.8mm overall length. The 20-degree S-Flo design is a key feature, helping to improve airflow into the combustion chamber. This updated design can make a notable difference in how efficiently your engine breathes, especially when you're pushing it hard.

Crafted from high-strength stainless steel, these valves are well-built to handle the heat and stress inside your F20C or F22C engine. The +1mm size means they are slightly larger than stock, which is a common modification to increase the valve opening area and allow more air-fuel mixture into the cylinder. This is a popular choice for builders looking to get more performance out of their Honda engines, whether for street use or track applications.

When rebuilding the top end of your F20C or F22C, using valves like these from Ferrea is a solid option. They are designed to fit right into the factory valve guides and seats, simplifying the installation process. Ensure you follow the manufacturer's guidelines for proper installation and valve lash settings to get the most out of them.
