Supertech Nissan SR20DE Manganese Bronze Exhaust Valve Guide 6mm Stem

Manganese bronze is a solid choice for exhaust valve guides, and this Supertech guide for the Nissan SR20DE uses it to help manage heat and wear. It's designed with a 6mm stem diameter, fitting specific SR20DE engine builds where this size is called for.

This guide is built to handle the demanding environment of an exhaust port. Manganese bronze offers good lubricity and wear resistance, which is important for keeping your valves sealing properly and preventing premature wear in the guide itself. It’s a well-built component that aims to keep your engine running smoothly.
