Nissan Fairlady/300ZX Z32 Balance Tube O-Ring (Small)

This O-ring is installed in the intake manifold assembly—typically at junction points such as balance tube or plenum connections—where it ensures an airtight seal between mating surfaces. It replaces earlier part numbers and is critical for preventing vacuum leaks that can negatively affect idle quality and engine performance. As a direct OEM-fit component, it maintains proper airflow integrity and sealing reliability, making it essential during intake servicing, plenum removal, or gasket replacement work on both USDM and JDM Z32 platforms.
