Supertech Nissan SR20DET/RB26 6mm Stem Manganese Bronze Intake Valve Guide - Single (Drop Ship Only)

If you're rebuilding the top end of your Nissan SR20DET or RB26 engine, getting the valve guides right is crucial for proper valve sealing and oil control. This single intake valve guide from Supertech is made from manganese bronze, a material known for its excellent wear resistance and self-lubricating properties, which helps reduce friction and extend the life of both the guide and the valve stem. It's designed to fit 6mm valve stems, ensuring a precise fit for these popular Nissan performance engines.

Manganese bronze is a solid choice for valve guides because it can handle the heat and stress inside the cylinder head while maintaining its shape and providing a smooth surface for the valve to slide through. This helps prevent valve sticking and ensures consistent performance. Installing new valve guides is a key step in any engine overhaul, especially when you want to restore or improve the engine's original breathing characteristics.
