Supertech Honda B18C1 5.5mm Stem Intake Valve Guide - Set of 8

If you're rebuilding the top end of your Honda B18C1 engine, getting the valve guides right is crucial for proper valve sealing and oil control. This set of eight intake valve guides from Supertech is designed to replace your worn-out originals, ensuring your valves move smoothly and maintain a good seal against the combustion chamber.

These guides are made with a focus on durability and precise fitment. The 5.5mm stem size is specific to the intake valves for your B18C1, and the OS1 designation indicates they are an oversize fit, which is common when reconditioning cylinder heads to ensure a tight seal. Supertech is known for producing well-built engine components, and this set is no exception, offering a solid option for your engine build.
