Using your K&N replacement air filter is super easy. First, locate your vehicle's factory air box. Open it up and take out the old air filter. Then, simply place the K&N filter in the same spot. Make sure it fits snugly and close the air box. That's it! As for maintenance, check the filter regularly. When it looks dirty, it's time to clean it. You can use K&N's recommended cleaning kit. Just follow the instructions on the kit to wash and re - oil the filter. Remember, always let the filter dry completely before putting it back in your vehicle. Also, keep in mind that while this filter is designed to last a long time, make sure to follow the warranty terms for any issues. And never use harsh chemicals or abrasive materials on the filter as it can damage the media.
