NITTO’s Bronze Valve Guides are manufactured from Phosphorus Bronze Alloy providing superior heat transfer, resistance to seizing and a lower friction coefficient than factory valve guides. Higher temperatures generated from performance engines and newer exotic blend fuels require a valve guide upgrade to maintain reliability, increase durability and lubrication to the valves under the most demanding conditions.
