Using your K&N replacement panel air filter is easy. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply drop in the new K&N air filter. Make sure it fits snugly and close the air box. When it comes to maintenance, the filter is washable and reusable. You can wash it with a mild soap and water solution. Let it dry completely before applying the special K&N filter oil. It's important to follow the oil application instructions carefully. Don't use harsh chemicals on the filter as it may damage the media. And always check the filter regularly for dirt and debris buildup. If you notice a significant drop in performance, it might be time to clean the filter. Remember, this filter is built to last, but proper care will ensure it keeps your engine running smoothly for the long haul.
