Using your K&N air filter is super easy. Just remove your old air filter from the factory air box and drop in the new K&N filter. It's designed to fit right in without any hassle. When it comes to maintenance, keep an eye on the filter's dirt level. When it looks dirty, it's time to clean it. You can wash the filter using a K&N filter cleaning kit. Just follow the instructions on the kit. After washing, let it dry completely before applying the K&N filter oil. Make sure to apply the oil evenly. As for storage, keep the filter in a dry place. Avoid exposing it to extreme heat or cold. And always refer to K&N's 10 - Year/Million Mile Limited Warranty if you have any concerns.
