Good To Know

Q: Does this fit both naturally aspirated and supercharged 1503 engines? A: This gasket is intended for the throttle body mounting surface on the listed 1503 applications. Verify your model and year before ordering.

Q: What happens if the gasket fails? A: A failed throttle body gasket can allow air leaks that cause rough idle or lean running. Replacing it restores a proper intake seal.
