Brian Crower Valve Guides - 6.6mm Mitsubishi 4G63/Evo Exhaust (Quantity of 8)

This set includes eight Brian Crower exhaust valve guides, specifically designed for 6.6mm valve stems. These guides are crucial for the proper function of your engine's valvetrain, ensuring the exhaust valves move smoothly and seal correctly within the cylinder head. They are a direct replacement for the factory guides in many popular Mitsubishi and DSM platforms.

Brian Crower is known for making well-built engine components, and these valve guides are no exception. They are made to precise tolerances, which helps maintain consistent valve alignment and prevents premature wear on both the valve stem and the guide itself. This attention to detail is important for engine longevity and performance, especially in modified applications where engines are pushed harder.

When rebuilding or upgrading your engine, replacing worn valve guides is a key step. These guides are designed to fit right into the cylinder head, making them a solid option for your build.
