Supertech Toyota Supra 2JZ Manganese Bronze Exhaust Valve Guide 6mm Stem OD 11.03mm

If you're rebuilding the top end of your Toyota Supra's legendary 2JZ engine, getting the valve guides right is crucial for proper sealing and performance. This Supertech exhaust valve guide is made from manganese bronze, a material known for its excellent wear resistance and ability to handle the heat of exhaust gases. It's designed with a 6mm stem outer diameter and an 11.03mm outer diameter, ensuring a precise fit within the cylinder head.

Manganese bronze is a solid choice for exhaust valve guides because it offers good lubricity, which helps prevent valve sticking and wear, especially under high temperatures. This guide is a direct replacement for your stock component, making installation straightforward when you're already deep into the engine build. Getting these details right contributes to the overall health and longevity of your 2JZ.
