Ferrea Honda B17A1/B18C1/C3 29mm 5.45mm 102.5mm +1mm Super Alloy Exh Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your Honda B17A1, B18C1, or B18C3 engine, especially for performance applications, you'll want to pay close attention to your valves. This Ferrea exhaust valve is crafted from a super alloy, which is a strong material designed to handle the high temperatures and stresses found in performance engines. It measures 29mm in diameter and is a +1mm oversize option, meaning it's slightly larger than stock to help improve airflow into the cylinder.

The valve stem is 5.45mm thick and the overall length is 102.5mm, with the +1mm oversize accounting for the increased head diameter. Using a well-built valve like this is crucial for maintaining proper compression and sealing, which directly impacts your engine's power and efficiency. Ferrea is known for making solid valvetrain components, and this exhaust valve is a popular choice for enthusiasts looking to get the most out of their Honda B-series engine.
