Brian Crower Nissan SR20DE(T) RWD 7.0mm Exhaust Valve Guides (Quantity of 8)

These 7.0mm exhaust valve guides from Brian Crower are made from a high-quality bronze alloy, a material chosen for its excellent wear resistance and ability to handle the heat generated by exhaust gases. They are specifically designed for the SR20DE and SR20DET engines found in the 1989-1998 Nissan 240SX, ensuring a precise fit within the cylinder head. Proper valve guide function is critical for maintaining valve sealing, preventing oil from entering the combustion chamber, and ensuring the valve operates smoothly within the head.

When rebuilding or modifying your SR20 engine, replacing worn valve guides is a crucial step for restoring lost compression and preventing oil consumption. These guides are well-built and intended to last, helping to keep your engine running strong. The 7.0mm sizing is specific to the exhaust valves on these popular Nissan engines, so make sure to confirm your application requires this size. Installing new valve guides typically requires specialized tools and knowledge, so it's often best handled by a professional mechanic or someone experienced with engine rebuilding.
