Using this K&N air filter is easy. First, open your vehicle's factory air box. Remove the old air filter carefully. Then, place the K&N drop - in filter in the same spot where the old one was. Make sure it fits snugly. Close the air box. That's it! When it comes to maintenance, check the filter regularly. If it looks dirty, you can wash it. Use a K&N filter cleaning kit. Wash the filter gently with the provided cleaner, then let it dry completely. After that, re - oil the filter using K&N filter oil. Always follow the instructions on the cleaning kit. Note that using non - K&N cleaning products might void the warranty. Also, make sure the filter is completely dry before reinstalling it to avoid any damage to your engine.
