Good To Know

Q: How often should a throttle body gasket be replaced? A: Replace it any time the throttle body is removed, and inspect it during intake service or whenever a vacuum leak is suspected. A worn or flattened gasket can cause idle and lean-condition symptoms.

Q: Does this gasket need sealant? A: No, a correctly formed throttle body gasket is designed to seal on its own once the fasteners are torqued to specification. Adding sealant can interfere with proper seating.

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