Supertech BMW S54 Manganese Bronze Intake/Exhaust Valve Guide 6mm Stem 12.03mm OD - Set of 12

This set includes twelve (12) Supertech valve guides, specifically made for the BMW S54 engine. These guides are designed to fit both intake and exhaust valves, featuring a 6mm stem diameter and a 12.03mm outer diameter. They are constructed from manganese bronze, a material known for its good wear resistance and ability to handle heat.

Manganese bronze is a solid choice for valve guides because it offers a good balance of hardness and lubricity, which helps reduce friction and wear on both the guide and the valve stem. This can contribute to better valve sealing and overall engine performance over time. Having a set of twelve ensures you have enough guides for all the valves in your S54 engine during a rebuild or repair.
