Ferrea Honda B17A1/B18C1/C3 33.5mm 5.47mm 25 Deg S-Flo +.5mm 6000 Series Intake Valve - Set of 8

Ferrea's 6000 Series Intake Valves are a solid option for your Honda B17A1, B18C1, or B18C3 engine build. This set includes eight valves, each featuring a 33.5mm head diameter and a 5.47mm stem, designed to fit your engine's specifications precisely. They are built with high-quality materials to handle the demands of performance applications.

These valves utilize Ferrea's S-Flo design with a 25-degree seat angle, which helps improve airflow into the combustion chamber. The valves are also +.5mm oversized, meaning they are slightly larger than stock to potentially improve sealing and performance when used with matching components. The 6000 Series construction is known for its durability and ability to withstand higher operating temperatures and pressures common in modified engines.
