Using your K&N oval air filter is a breeze. First, locate your vehicle's factory air box. Open it up and take out the old air filter. Then, simply place the K&N air filter in the same spot as the old one. Make sure it fits snugly and close the air box. As for maintenance, it's recommended to clean the filter every 50,000 miles, depending on your driving conditions. If you often drive in dusty areas, you may need to clean it more frequently. To clean, use a K&N air filter cleaning kit. Remove the filter, spray the cleaner on it, let it soak for a few minutes, then rinse it gently with water. Let it dry completely before applying the K&N filter oil evenly. When handling the filter, be gentle to avoid damaging the cotton media. Always refer to the K&N 10 - Year/Million Mile Limited Warranty for any concerns.
