Supertech Toyota 4AGE Manganese Bronze Int/Exh Valve Guide 6mm Stem (Use w/Oil Seal VS-T6SM)

This is a Supertech Manganese Bronze intake and exhaust valve guide for the Toyota 4AGE engine. It's designed for a 6mm valve stem and is meant to be used with the VS-T6SM oil seal. If you're rebuilding the top end of your 4AGE, replacing the valve guides is a crucial step to ensure proper valve sealing and oil control.

Manganese bronze is a well-built material for valve guides because it offers good wear resistance and self-lubricating properties, which helps reduce friction between the valve stem and the guide. This can lead to improved valve train longevity and consistent performance. This guide is a direct replacement for the stock unit, making installation straightforward when you have the cylinder head disassembled.
