Valve and Valve Guides

Megawatts offers a dedicated authentic range of Valve and Valve Guides. Valves are mechanical components that open and close to regulate the flow of gases into and out of an engine's cylinders. There are two main types: intake valves (for air/fuel mixture) and exhaust valves (for exhaust gases). 

Valve Guides are small cylindrical sleeves that the valve stems slide through. They keep the valve perfectly aligned as it moves, help cool the valve by transferring heat away from it and work with valve stem seals to prevent oil from leaking past the valve stem into the combustion chamber.

Each valve guide is built by OEM quality for accurate alignment, reduced wear, and smooth valve movement to support efficient combustion and extend engine life.
