Installing your K&N drop - in air filter is a breeze. First, open your vehicle's factory air box. It's usually easy to find under the hood. Carefully remove the old air filter. Then, take your new K&N air filter and place it in the same spot where the old one was. Make sure it fits snugly. Close the air box back up. That's it! You're ready to enjoy better airflow and performance. As for maintenance, every so often, check the filter. If it looks dirty, you can wash it. K&N provides cleaning kits that are easy to use. Just follow the instructions on the kit. Remember, this filter is built to last the life of your vehicle, but proper care will keep it performing at its best. And don't forget, it's backed by a 10 - Year/Million Mile Limited Warranty, so you can have peace of mind while driving. Also, always refer to your vehicle's manual if you have any specific questions about air filter installation or maintenance.
