Using your K&N air filter is a breeze. First, locate your vehicle's factory air box. Open it up and take out the old air filter. Then, simply place the K&N filter in its spot. It's designed to fit perfectly, so you won't have any trouble. As for maintenance, you don't need to replace the filter often. When it gets dirty, you can wash it. Use a K&N filter cleaning kit. Soak the filter in the cleaner, then rinse it gently with water. Let it dry completely before oiling it with K&N filter oil. Make sure to follow the oiling instructions on the bottle. When handling the filter, be careful not to damage the cotton media. And always remember, this filter is backed by a great warranty, so if you have any issues, K&N's got you covered.
