Using this cold air intake kit is simple. First, locate the stock intake system in your 2003 - 2007 Dodge Ram 2500/3500 with a 5.9L Cummins engine and carefully remove it. Then, install the Banks' Ram - Air Intake Kit following the provided instructions. When it comes to maintenance, you can periodically check the filter. If it's dirty, clean it according to the type of filter you have (dry or oiled). For the dry filter, gently tap it to remove large debris and then use compressed air to blow out the rest. For the oiled filter, use a special filter cleaning kit. Make sure to keep the enclosed housing clean and free of any blockages. Also, check the 4.5' bellows regularly for any signs of wear or damage. If you notice any issues, contact the manufacturer. Remember, this kit is designed not to cause fault or error codes, but if you do encounter any problems, consult a professional mechanic.
