Using your K&N air filter is easy. First, locate your factory air box. Open it up and take out the old filter. Then, simply drop the K&N filter into the air box. Make sure it fits snugly and close the air box. That's it! When it comes to maintenance, keep an eye on the filter. If it looks dirty or clogged, it's time to clean it. You can use a K&N filter cleaning kit. Just follow the instructions on the kit to wash and re - oil the filter. Don't use harsh chemicals or cleaners as they can damage the filter. Also, check the filter regularly, especially if you drive in dusty or dirty conditions. And remember, this filter is built to last, but proper care will keep it performing at its best for your vehicle's entire lifespan.
