Supertech valve guides are manufactured from high quality Manganese Bronze for sport compact and domestic applications. Our valve guides are designed to be used in combination with our low friction black nitride valves to provide the best solution for both performance and durability. For exhaust valve guides designed to be used for high powered engines that need a better thermal transfer coefficient, we use a copper alloy guide. Copper has about a 3x higher thermal transfer rate than manganese bronze.
