Nissan Fairlady/300ZX Z32 Lower Intake Heated Spring Washer

This spring washer is installed on the lower intake manifold hardware, where it helps maintain consistent clamping force as the engine heats and cools. Its “heated” or spring design compensates for thermal expansion, ensuring the intake remains properly sealed against the engine. This prevents vacuum leaks and maintains stable airflow and engine efficiency. Typically used in multiple locations (about 10 required), it is a direct OEM-fit component critical for proper intake manifold sealing and long-term reliability.
