This listing is for one Supertech manganese bronze intake valve guide designed for Honda D and K series engines with 5.5mm valve stems.

When you're rebuilding the top end of your Honda engine, replacing worn valve guides is a key step to restoring compression and preventing oil consumption.

Manganese bronze is a well-known material for valve guides because it offers good wear resistance and lubricity, which helps reduce friction between the valve stem and the guide.

Proper installation is important; these guides are typically pressed into the cylinder head, so having the right tools and technique will ensure a solid fit and long service life.
