*Each single quantity includes 8 total units. For a 16 valve engine, use a quantity of 2.

Supertech valve guides are precision-machined from high quality Manganese Bronze material.  They're designed to be used in combination with low friction black nitrided 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 3 times higher thermal transfer than Manganese Bronze. Regardless of your needs supertech has the right valve guide for your application.

**These seals are made to fit 6.0mm stock or stock replacement valves
