If you're rebuilding the top end of your Honda B17A1, B18C1, or B18C3 engine, choosing the right valves is crucial for performance and reliability. These Ferrea Competition Plus intake valves are designed to handle the demands of a performance build, offering improved airflow and durability over stock components. They are a solid option for anyone looking to get the most out of their engine.

Ferrea uses high-quality steel for these valves, ensuring they can withstand the heat and stress of combustion. The S-Flo design helps improve airflow into the cylinder, which can lead to better power output. This set includes eight intake valves, each measuring 34mm in diameter with a 5.47mm stem, and they are 1mm oversized to help maximize flow when used with appropriately sized ports. The 25-degree seat angle is a common performance feature that aids in sealing and airflow.

When installing these valves, it's important to ensure your valve guides and seats are in good condition and properly matched to the valve size. Using these performance valves is a step towards achieving a more powerful and responsive engine.
