Valve-guide set of 8 (Manganese)
C-AJJ4037- MINI VALVE GUIDE SET(8) MANGONESE BRONZE TYPE
A must for any competition car! Although Silicon bronze valve guides were used for their extremely good wear values, they were very hard and not user friendly when fitting. Were possible we now use the Manganese bronze guides which have good cutting properties and good wear characteristics and are original equipment on Porsche and Mercedes.
