Supertech Nissan SR20DET Manganese Bronze Exhaust Valve Guide 6mm Stem - Set of 8

Manganese bronze is a strong material for valve guides, and that's what these Supertech guides are made from. They're designed for the Nissan SR20DET engine and feature a 6mm stem diameter, fitting the exhaust side of your engine. This set includes eight guides, enough to replace all the exhaust valve guides in your SR20DET.

Using the right valve guides is important for proper valve sealing and to prevent wear on both the guide and the valve stem. Manganese bronze offers good wear resistance and lubricity, which helps keep things running smoothly inside your engine. These guides are a direct replacement for the stock ones, making installation straightforward if you're rebuilding or refreshing your SR20DET's cylinder head.
