Ferrea Honda H22A1/A4 36mm 5.48mm 106.85mm 20 Deg S-Flo +1mm Flat Hd 5000 Series Int Valve- Set of 8

If you're rebuilding the top end of your Honda H22A1 or H22A4 engine, you'll want to consider these Ferrea 5000 Series intake valves. These are designed to handle the demands of performance builds, offering a solid option for getting your engine breathing right again. They feature a 36mm head diameter and a 5.48mm stem, with a +1mm oversized design to help improve airflow into the combustion chamber.

Ferrea uses a strong, well-built steel alloy for these valves, which is crucial for durability under high temperatures and pressures. The S-Flo design with a 20-degree back angle is intended to help improve flow characteristics, especially when paired with other engine modifications. The flat head design is standard for intake valves and works well with most piston and camshaft combinations. This set includes eight valves, enough for a complete engine.
