If you have a performance motor, turbo or nitrous the heat destroys the OEM valve guides quickly. These manganese bronze guides are just what you need at a price that's unbeatable for the quality. Why settle for OEM when you can have ND? The standard guide also is very brittle, if a valve gets bent and you don't replace the guides they can crack and fall into the cylinder causing untold damage after the repair!
