This cabin air filter door kit contains a door that matches the fit and function of the original equipment filter on specified late-model Chrysler, Dodge, Jeep and Ram vehicles. Certain models were not equipped with a cabin air filter. For those vehicles, the included utility knife, cutting template and detailed instructions may be used to add a filter to the factory HVAC box, which is ready to accept the door in this kit. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
