MAINTAINING YOUR VEHICLE 333 A visual inspection of the air cleaner filter element is never recommended under normal circumstances. A badly restricted element may appear clean while a soiled element may be quite effective in filtering particles without restricting air flow. Rely on the Filter Minder™ to determine when a filter change is necessary. After a new filter element is inserted, press the rubber button on the top of the Filter Minder™. This action will reset the yellow disc to the clean position. CAUTION! When using an engine cleaner or a degreaser, be sure to wrap and tape the Filter Minder™ to protect the plastic housing from damage and discoloration. NOTE: Many aftermarket performance air filter elements do not adequately filter the air entering the engine. Use of such filters can severely damage your engine and such damage is not covered by the manufacturer's warranty. 7
