Using your K&N air filter is easy. First, find your factory air box under the hood of your 2010 - 2016 Cadillac SRX. Open the air box and remove the old filter. Then, simply drop in the K&N replacement filter. Make sure it fits snugly and close the air box. As for maintenance, it's recommended to clean the filter every 50,000 - 100,000 miles, depending on your driving conditions. When cleaning, use K&N's filter cleaning kit. Follow the instructions on the kit to gently wash the filter and let it dry completely before applying the oil. Keep in mind that this filter is reusable, so take good care of it. Also, if you notice any damage to the filter, contact K&N for further assistance.
