Using your K&N air filter is a breeze. First, find your vehicle's factory air box. Open it up, remove the old air filter, and then simply drop in your new K&N filter. Make sure it fits snugly. When it comes to maintenance, the great thing about these filters is that they're washable and reusable. Every so often, check the filter for dirt and debris. If it looks dirty, take it out and wash it with a mild cleaner. Rinse it thoroughly and let it dry completely. Once dry, re - oil the filter according to the instructions on the K&N kit. Remember, keep your filter away from sharp objects to avoid damage. With proper use and maintenance, your K&N filter will serve you well for the life of your vehicle.
