5000 Series Intake and Exhaust Valves

The Ferrea 5000 Series Valves offer a budget-friendly option for enhancing your engine's valvetrain, engineered to perform under demanding conditions such as high RPMs and elevated spring pressures. Each valve is meticulously machined within Ferrea's advanced CNC facilities, guaranteeing precise tolerances. These valves feature a one-piece forging for superior strength and durability. They are equipped with hard chrome stems, which reduce friction and wear, further contributing to their robust performance. The flat face design is standard for this series, and the valves are fully CNC machined for optimal performance. Designed for specific Honda applications, these valves are compatible with the H22A1 and H22A4 engines. Key specifications include an intake valve head diameter of 35.0mm and an exhaust valve head diameter of 30.0mm, with both being STD size. The intake valve length measures 106.85mm, while the exhaust valve length is 107.1mm. The valve stem diameter for both intake and exhaust is consistently 5.48mm.
