Brian Crower Honda B18A/B, B20B, H23 6.6mm Intake Valve Guides (Quantity of 8)

If you're rebuilding the top end of your 1990-2001 Acura Integra, especially if you're working with a B18A/B, B20B, or H23 engine, new valve guides are a critical part of the job. These Brian Crower intake valve guides are designed to replace your worn-out originals, ensuring your valves seat correctly and operate smoothly within the cylinder head. Proper valve guide function is essential for maintaining compression, preventing oil from entering the combustion chamber, and allowing the engine to breathe efficiently.

Brian Crower is known for making well-built engine components, and these valve guides are no exception. They feature a 6.6mm stem diameter, which is the correct size for the specified Honda and Acura engines. Installing new guides helps restore the precision fit of the valves, which can make a noticeable difference in engine performance and longevity. This set includes eight guides, enough for a typical 4-cylinder cylinder head.
