Using your K&N air filter is easy. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply drop the K&N filter into the air box and close it back up. It's a quick and simple process. When it comes to maintenance, check the filter regularly. If it looks dirty, it's time to clean it. You can use K&N's specific filter cleaning kit. Just follow the instructions on the kit to wash the filter gently with the provided cleaner and then let it dry completely. After that, re - oil the filter using K&N's filter oil. Make sure not to over - oil it. Keep in mind that this filter is designed to last the life of your vehicle, but proper maintenance will ensure it performs at its best. Also, always handle the filter with clean hands to avoid getting dirt on it.
