Help ignition timing respond to engine vacuum as your Dodge or Plymouth was designed to with the Standard Ignition distributor vacuum advance VC-184. This vacuum advance control is a direct-fit replacement for the listed applications, which cover many vehicles, including the 1973-1976 Dodge Dart, 1973-1976 Plymouth Duster and 1976-1978 Dodge Aspen.
A vacuum advance mounts on the distributor and uses engine vacuum to advance ignition timing when vacuum is present, such as at light throttle. Signs it may need replacing include hesitation or flat response at part throttle, reduced fuel economy, or a unit that no longer holds vacuum. If a failed vacuum advance is the cause, this unit replaces it; check vacuum hoses and other ignition components as part of your diagnosis.
Fitment covers a wide range of Dodge and Plymouth car, van and truck models. See the "Vehicles it fits" section for the complete list of years, models and engines.
