Using your K&N air filter is super easy. Just remove your old filter from the factory air box and drop in the new K&N filter. Make sure it fits snugly. When it comes to maintenance, these filters are washable and reusable. Every so often, check the filter for dirt and debris. If it looks dirty, you can wash it with a mild cleaner. After washing, let it dry completely and then re - oil it according to the instructions on the product. This will keep it performing at its best. And remember, since it's backed by a 10 - Year/Million Mile Limited Warranty, you can use it with confidence throughout your vehicle's lifespan.
