Using your K&N air filter is a breeze. First, locate your factory air box. Open it up and carefully remove the old air filter. Then, simply drop in the new K&N filter. Make sure it fits snugly and close the air box. That's it! For maintenance, it's recommended to clean the filter every 50,000 to 100,000 miles, depending on your driving conditions. To clean it, use K&N's special cleaning kit. Spray the cleaner on the filter and let it soak for a few minutes. Then, rinse it gently with water. Let it dry completely before re - oiling it with the provided oil. When re - oiling, follow the instructions on the oil bottle. Always check the filter regularly for any signs of damage. If you notice any tears or excessive dirt that can't be cleaned, it might be time to replace the filter. Keep in mind that proper installation and maintenance will ensure you get the most out of your K&N air filter and enjoy improved vehicle performance for a long time.
