Using your K&N air filter is easy. First, locate your vehicle's factory air box. Open it up and remove the old air filter. Then, simply drop the K&N filter into place and close the air box. That's it! For maintenance, you can wash the filter when it gets dirty. Use a K&N filter cleaning kit and follow the instructions on the kit. Make sure to let the filter dry completely before re - oiling it. Don't over - oil the filter as this can cause issues. When you're done, reinstall the filter in your air box. Keep in mind that this filter is designed to last a long time, but regular checks and maintenance will ensure it continues to perform at its best.
