Using your K&N air filter is a breeze. First, find your vehicle's factory air box. Then, simply remove the old air filter and drop in the new K&N filter. It's designed to fit right in without any major adjustments. When it comes to maintenance, since it's washable and reusable, you don't have to buy a new filter often. Every few months or when it looks dirty, take it out and wash it with a mild soap and water. Let it dry completely, and then re - oil it using K&N's recommended filter oil. Make sure to follow the oiling instructions on the bottle. As for the warranty, keep your purchase receipt handy. If there are any issues within the 10 - year or million - mile limit, K&N has got you covered. Just reach out to their customer service and they'll guide you through the process.
