Oil seepage around the spark plug tubes can create messy wells and complicate routine maintenance on the Z32. The genuine Nissan Spark Plug Tube Seal, Upper Outer (part number 13291-30P00) is the factory upper seal used on the Fairlady Z / 300ZX Z32, designed to seal the top of the spark plug tube against the valve cover.
This OEM seal forms the outer barrier at the upper end of each tube, helping keep oil from migrating into the plug wells from above. Over time the original seals can harden, flatten, or crack, reducing their effectiveness and allowing oil to collect around the spark plugs. Replacing them with the correct genuine Nissan upper outer seals restores the intended sealing arrangement and supports cleaner, drier plug wells. These seals are commonly renewed whenever the valve covers are removed or when oil intrusion is found during plug service.
Whether you are correcting existing leakage, performing valve cover work, or refreshing aging seals as preventive maintenance, this part is an important detail for reliable ignition system upkeep. At Terra Firma Automotive, we supply this genuine Nissan Spark Plug Tube Seal for Z32 owners who prefer authentic OEM sealing components. Choose Terra Firma Automotive for correct-fit Nissan parts that help keep oil contained on the Fairlady Z and 300ZX.
