Good To Know

Q: Does this gasket need sealant during installation? A: No, this is a dry-fit gasket, so keep the mating surfaces clean and install it without RTV or gasket sealer unless the service manual states otherwise.

Q: What symptoms point to a failed throttle body gasket? A: A leaking gasket can cause a rough idle, an erratic idle speed, or a lean condition flagged by the engine management system, so any of these signs makes it worth inspecting the seal.

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