Using your K&N drop - in air filter is easy. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply place the K&N filter in the same spot where the old one was. Make sure it fits snugly and close the air box. As for maintenance, check the filter regularly. If it looks dirty, it's time to clean it. You can use K&N's air filter cleaning kit. Just follow the instructions on the kit to wash the filter gently with the provided cleaner and let it dry completely before oiling it again with the oil from the kit. Remember to always use genuine K&N cleaning and oiling products to keep your filter in top shape. Also, when installing or cleaning the filter, be careful not to damage the delicate cotton media. And if you have any questions, K&N's customer service is always there to help.
