Supertech Subaru EJ20/EJ25 Manganese Bronze Intake Valve Guide 6mm Stem - Set of 8

This set includes eight manganese bronze intake valve guides, each designed for a 6mm stem, for your Subaru EJ20 or EJ25 engine. Valve guides are crucial for ensuring your intake valves move smoothly and seal properly within the cylinder head. When they wear out, you can experience issues like oil consumption, poor performance, and even valve sealing problems.

Manganese bronze is a well-known material for valve guides because it offers good wear resistance and lubricity, which helps reduce friction and extend the life of both the guide and the valve stem. These guides are a direct replacement for your stock components, making installation straightforward for anyone rebuilding or refreshing their engine's top end. Having a set of eight means you'll have enough for all intake ports on your engine.
