Using your K&N air filter is a breeze. First, open your vehicle's factory air box. Then, take out the old air filter and simply drop in the new K&N filter. Make sure it fits snugly in place before closing the air box. As for maintenance, you don't need to replace the filter often. Instead, when it gets dirty, you can wash it. Use a K&N air filter cleaner according to the instructions on the cleaner bottle. After cleaning, let it dry completely before re - oiling it with K&N filter oil. This will keep your filter in top shape. One important thing to note is that always follow the vehicle manufacturer's maintenance schedule for other parts of your car, even though your K&N filter is long - lasting. Also, store the filter in a clean, dry place when not in use.
