Good To Know

Q: Does this gasket need sealant to install? A: No, it is designed to seal on its own when the throttle body is torqued to spec, though clean mating surfaces are essential. Q: How do I know my old gasket has failed? A: Common signs include rough idle, lean running, and whistle noises from the intake area of the 1503 engine.

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