Using your K&N air filter is easy. Just remove your old air filter from the factory air box and drop in the K&N filter. Make sure it fits snugly. When it comes to maintenance, you can wash and reuse this filter. Check it regularly for dirt and debris. If it looks dirty, remove it from the air box and wash it with a mild detergent and water. Let it dry completely before oiling it again. Don't use too much oil, as it can cause issues. Also, always follow the oiling instructions that come with the filter. Remember, this filter is designed to last the life of your vehicle, but proper care will keep it performing at its best.
