Supertech Toyota/Sicon Manganese Bronze Intake Valve Guide 5.5mm Stem

Supertech is known for making performance engine components, and this intake valve guide is a good example of their work. It's built for engines that use a 5.5mm stem diameter on their intake valves. This guide is crucial for ensuring your intake valve moves smoothly and stays properly aligned within the cylinder head as it opens and closes.

This particular guide is made from manganese bronze, a material chosen for its good wear resistance and ability to lubricate itself. This helps reduce friction between the valve stem and the guide, which can improve valve action and potentially extend the life of both components. It's a solid option for anyone rebuilding or upgrading their engine's valvetrain.
