Ferrea Honda B17A1/B18C1/C3 33mm 5.47mm 25 Deg S-Flo Stk Flat Head 5000 Series Int Valve - Set of 8

These Ferrea 5000 Series intake valves feature a 33mm head diameter and a 5.47mm stem, designed for specific Honda B-series engines like the B17A1, B18C1, and B18C3. The 25-degree S-Flo design helps improve airflow into the cylinder by reducing turbulence around the valve head.

Constructed from high-strength stainless steel, these valves are built to withstand the heat and stress of performance engine operation. The flat head design is a stock replacement style, making them a straightforward choice for rebuilds or upgrades where maintaining a similar combustion chamber profile is desired. This set includes eight valves, enough for a typical 4-cylinder engine.
