Ferrea Honda B18A1 31.5mm 6.57mm 105.5mm Dish +.5mm Comp Plus Int Valve - Single (Drop Ship Only)

This Ferrea Comp Plus intake valve is made with a 31.5mm head diameter and a 6.57mm stem, designed to fit Honda B18A1 engines. The valve's specific dimensions and dish design are intended to help improve airflow into the combustion chamber, which can make a difference in how your engine performs, especially if you're rebuilding the top end or looking for better breathing. Ferrea uses specific materials and heat-treating processes to ensure these valves can handle the demands of an engine.

The +.5mm compression dish on this valve is a detail that helps optimize the combustion chamber volume. This means it's a well-built component that's meant to work with the specific geometry of the B18A1 cylinder head. When you're putting an engine back together, using valves that are made to precise specifications like these can help ensure everything seals properly and performs as expected. It's a single valve, so you'll need to order the correct quantity for your application.
