Supertech Honda B/H Series Manganese Bronze Exhaust Valve Guide 6.0mm Stem - Single (Drop Ship Only)

Supertech is known for making solid internal engine components, and this exhaust valve guide for Honda B and H-series engines is no exception. If you're rebuilding the top end of your Honda, these guides are a crucial part of ensuring your valves move smoothly and seal properly. This particular guide is made from manganese bronze, a material that offers good wear resistance and heat dissipation, which is important for exhaust valves that run hotter than intake valves.

This guide is designed for a 6.0mm stem diameter, a common size for many performance and stock Honda applications. When you're installing these, make sure the valve stem seal surface is clean and free of debris. A clean installation helps ensure the longevity of both the guide and the valve itself.
