Nissan Fairlady/300ZX Z32 Spark Plug Tube Seal, Upper Outer

This is the OEM spark plug tube seal for 1990–1996 Nissan 300ZX and Fairlady Z models with the VG30DE and VG30DETT engines. These small rubber seals sit at the bottom of the spark plug tube ornaments (guides) where they meet the valve cover, preventing oil from leaking down into the spark plug wells. On aging Z32 engines, they often harden, shrink, or crack, allowing oil to accumulate around the plugs and potentially causing misfires or messy ignition components. Replacing them with this genuine Nissan part ensures a clean, leak-free seal and is commonly done during valve cover or spark plug service for better reliability.
