Ferrea Honda K20C1 36mm 5.48mm 117.25mm 20 Deg S-Flo +1mm 6000 Series Intake Valve - Set of 8

Ferrea is well-known for making strong internal engine components, and these 6000 Series intake valves are a prime example. If you're working on a Honda K20C1 engine, these valves are built to handle the demands of performance builds. They feature a 36mm head diameter and a 5.48mm stem, with an overall length of 117.25mm, designed to fit precisely in the K20C1 cylinder head.

These valves use Ferrea's S-Flo design with a 20-degree back angle, which helps improve airflow into the combustion chamber. The +1mm sizing indicates they are slightly larger than stock, often used when porting or modifying the cylinder head to maximize flow. The 6000 Series material is chosen for its durability and ability to withstand higher temperatures and pressures found in performance applications. This set includes eight valves, enough for a complete cylinder head.
