Supertech Toyota 4AGE Manganese Bronze Int/Exh Valve Guide 6mm Stem (Use w/VS-T6SM) - Set of 8

This set includes eight manganese bronze valve guides for your Toyota 4AGE engine. These guides are designed for 6mm valve stems and are intended to be used with Supertech's VS-T6SM valve seats. Manganese bronze is a well-known material for valve guides because it offers good wear resistance and lubricity, which helps your valves move smoothly and reduces friction.

When you're rebuilding or refreshing the top end of your 4AGE, new valve guides are a critical component. They ensure your valves seal properly and guide them accurately into their seats. Using a material like manganese bronze helps dissipate heat and provides a durable surface for the valve stem to slide against, contributing to the longevity of your engine's valvetrain.
