Ferrea Honda B18A1/B1/B20A 31mm 6.57mm 105.5mm 20 Deg S-Flo Dish Stk Comp Plus Int Valve - Set of 8

Ferrea is well-known for making strong valvetrain components, and these Comp Plus intake valves are a great example of that. If you're rebuilding the top end of your Honda B18A1, B1, or B20A engine, these valves are built to handle the demands of performance builds. They feature a 31mm head diameter and a dish shape, designed to work with stock compression setups.

These valves are made from a durable material that holds up well under heat and stress. The S-Flo design helps improve airflow into the cylinder, which can make a difference in how your engine breathes. With a 6.57mm stem and a 105.5mm overall length, they are made to fit right into your existing valvetrain setup, assuming you're using stock-style components. This set includes eight valves, enough for a complete cylinder head.
