Ferrea Honda H22A1/A4 35mm 5.48mm 106.85mm 20 Deg S-Flo Stk 6000 Series Intake Valve - Set of 8

These Ferrea 6000 Series intake valves are made from a strong, high-grade stainless steel alloy, specifically chosen for its ability to handle the heat and stress of performance engine builds. With a 35mm head diameter and a 5.48mm stem, they are designed to fit Honda H22A1 and H22A4 engines, offering an improved flow path compared to stock components.

The 20-degree S-Flo seat angle is a notable design choice that helps reduce turbulence as air enters the cylinder, contributing to better combustion efficiency. Each valve measures 106.85mm in overall length, ensuring proper geometry within the cylinder head. This set includes eight valves, providing a complete replacement for your engine's intake side.

When rebuilding or modifying your H22A1 or H22A4, using valves built to these specifications can make a difference in how your engine performs. It's always a good idea to check your cylinder head's valve seat condition and ensure it's ready to properly seat these new valves for optimal sealing.
