Supertech Nissan VR38 Manganese Bronze Intake Valve Guide 6mm Stem - Set of 12

Supertech is known for making well-built internal engine components. This set of 12 manganese bronze intake valve guides is specifically made for the Nissan VR38 engine. These guides are crucial for proper valve operation, ensuring the valve stem moves smoothly and stays aligned within the cylinder head.

Manganese bronze is a solid material choice for valve guides because it offers good wear resistance and lubricity, which helps reduce friction and wear on both the guide and the valve stem. This set is designed for a 6mm valve stem diameter, which is common in many performance applications. Replacing worn valve guides is a key step when rebuilding or refreshing the top end of your engine, helping to restore compression and prevent oil consumption.
