Using your K&N air filter is a breeze. First, locate your vehicle's factory air box. Open it up and carefully remove the old air filter. Then, simply drop in the new K&N filter in the same position as the old one and close the air box. It's that easy! When it comes to maintenance, check the filter regularly. If it looks dirty, it's time for a clean. You can wash it using a K&N filter cleaning kit. Follow the instructions on the kit to ensure proper cleaning. Let the filter dry completely before re - installing it. As for storage, keep it in a dry place when not in use. Remember, don't use any harsh chemicals on the filter as it can damage the oiled cotton media. Also, always refer to your vehicle's manual for any specific installation or maintenance advice.
