Supertech Nissan SR20DET / RB26 Manganese Bronze Intake Valve Guide 6mm Stem - Set of 12

This set includes 12 manganese bronze intake valve guides for Nissan SR20DET and RB26 engines, each designed for a 6mm valve stem. These guides are crucial for proper valve operation, ensuring the valve moves smoothly and stays centered within the cylinder head. Manganese bronze is a well-known material for this application due to its good wear resistance and ability to lubricate itself, which helps reduce friction and heat buildup.

When rebuilding or modifying an SR20DET or RB26 engine, replacing the valve guides is often a necessary step to ensure optimal performance and longevity. These Supertech guides are made to fit SR20DET and RB26 cylinder heads, providing a solid option for those looking to restore or enhance their engine's valvetrain. The 6mm stem size is specific to the intake valves on these popular Nissan engines.
