Nissan Fairlady/300ZX Z32 Spark Plug Tube Seal, Lower Inner

This is the OEM spark plug tube seal for 1990–1996 Nissan 300ZX and Fairlady Z models with the VG30DE and VG30DETT engines. These rubber seals sit where the spark plug tubes pass through the valve cover, preventing oil from leaking into the spark plug wells. On higher-mileage Z32s, they commonly harden, crack, or shrink, causing oil to pool around the spark plugs and leading to misfires or messy engine bays. Replacing them with this genuine Nissan part restores a clean, leak-free seal and improves ignition reliability. It’s a smart, inexpensive maintenance item often done during valve cover gasket service. Tip: Most owners replace all 4 at the same time along with the valve cover gaskets.
