Using your K&N air filter is super easy. First, find your vehicle's factory air box. Open it up, take out the old air filter, and drop in the K&N replacement filter. Make sure it fits snugly in place. Close the air box, and you're good to go. When it comes to maintenance, these filters are washable and reusable. Every once in a while, check the filter for dirt and debris. If it looks dirty, remove it from the air box. Wash it gently with mild soap and water, then let it dry completely. After that, re - oil the filter according to the instructions on the K&N oil bottle. As for the oil, always use K&N's recommended filter oil. And don't forget, this filter is backed by a 10 - Year/Million Mile Limited Warranty, so you can use it with confidence throughout your vehicle's life.
