Using your K&N air filter is easy. Just remove your old filter from the factory air box and drop in the new K&N filter. It's designed to fit right in without any complicated tools. As for maintenance, every 50,000 to 100,000 miles (depending on your driving conditions), you'll want to clean the filter. Use K&N's special cleaning kit. First, spray the cleaner on the filter and let it soak for a few minutes. Then, gently rinse it with water. Don't use too much pressure as it could damage the filter. After rinsing, let it dry completely. Once dry, apply the K&N filter oil evenly. A well - maintained filter will keep your engine running smoothly. One important note: avoid using any other cleaning products or oils that aren't recommended by K&N as they could harm the filter and void the warranty.
