Supertech Nissan SR20DET Manganese Bronze Intake Valve Guide 6mm Stem - Set of 8

If you're rebuilding the top end of your Nissan SR20DET engine, these Supertech intake valve guides are a solid choice. They're made from manganese bronze, a material known for its good wear resistance and ability to handle the heat and friction inside the cylinder head. This set includes eight guides, which is exactly what you need for a complete intake valve job on your SR20DET.

Manganese bronze is a popular material for valve guides because it offers a good balance of hardness and lubricity. This means it can withstand the constant movement of the valve stem without excessive wear, while also providing a smooth surface for the stem to slide against. Having well-fitting, durable valve guides is crucial for proper valve sealing and overall engine performance. These guides are designed to fit the 6mm valve stems common on the SR20DET.
