Nissan Fairlady/300ZX Z32 Upper Plenum Gasket

This gasket seals the mating surface between the upper plenum and lower intake manifold, ensuring an airtight connection for proper airflow distribution. It is critical for maintaining correct air-fuel mixture, idle stability, and overall engine efficiency. Typically replaced whenever the plenum is removed (such as during injector or maintenance work), it prevents vacuum leaks that can cause rough running or performance issues. As a direct OEM replacement, it supersedes earlier gasket part numbers and provides factory-correct fitment and sealing reliability.
