Good To Know

Q: Do I need to replace this gasket every time I remove the throttle body? A: Yes, gaskets are single-use crush items. Reusing one risks an air leak and rough running.

Q: Is any sealant required during installation? A: No, install the gasket dry on a clean mating surface and torque the fasteners to specification.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
