Open the hood and locate the airbox, which is usually near the front of the engine bay. Release the clips or screws securing the airbox lid—these may be simple clamps or require a screwdriver. Carefully lift the lid and remove the old air filter, noting its orientation. Inspect the airbox for debris and wipe it clean with a dry cloth. Place the new Hellcat air filter into the airbox, ensuring it sits snugly and aligns with the grooves or edges. If using an oiled filter, avoid over-oiling, as excess oil can damage sensors. Secure the airbox lid back in place, fastening the clips or screws firmly to prevent air leaks. Finally, start the engine and listen for unusual sounds, indicating a proper installation. This process enhances airflow immediately, with no need for tuning in most cases, though performance gains may be more noticeable after a few drive cycles.
Maintenance and Cleaning Tips for Long-Lasting Performance
Proper maintenance of your Hellcat air filter is crucial for sustained performance and engine protection. For reusable filters, such as cotton gauze types, clean them every 30,000 to 50,000 miles, or more often if driving in dirty conditions. Use a dedicated air filter cleaning kit, which includes a cleaner solution and oil. Start by removing the filter from the airbox. Spray the cleaner evenly on both sides, allowing it to soak for 10-15 minutes to dissolve dirt. Rinse gently with low-pressure water from the inside out to avoid damaging the media, and let it air-dry completely—never use heat sources. Once dry, apply the filter oil in a thin, even layer, covering the entire surface; the oil enhances filtration by trapping particles. Reinstall the filter only when it's fully dry and oiled. For disposable filters, replace them according to the manufacturer's schedule, typically every 15,000 to 30,000 miles, or sooner if visibly dirty. Regularly inspect the airbox for leaks or damage, and check the filter during oil changes. Neglecting maintenance can lead to clogging, reduced airflow, and engine issues, so adhere to a routine for best results.
