Every few thousand miles, take a look at the filter. If it's dirty, you can clean it with a mild filter cleaner. Just make sure it's completely dry before putting it back in. Also, keep an eye on the heat shield and intake tube. If you notice any damage or cracks, it's a good idea to replace the part right away to keep your system working at its best.
