Good To Know

Q: How do I know if my throttle body gasket needs replacing? A: Common signs include a rough or hunting idle, lean codes, or visible cracks and flattening on the old seal. Replacing the gasket during throttle body service is the surest fix.

Q: Does this gasket require any sealant during install? A: No, the pre-formed gasket installs dry between clean mating surfaces. Confirm the mounting faces are free of old material and residue before assembly.

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