Using your K&N air filter is easy. First, open your vehicle's factory air box. Remove the old air filter and place the K&N filter in its place. Make sure it fits snugly and close the air box. That's it! For maintenance, check the filter regularly. If it looks dirty, it's time to clean it. You can use K&N's special cleaning kit. Wash the filter gently with the cleaner and let it dry completely. Then, re - oil the filter using K&N's filter oil. When handling the filter, be careful not to damage the delicate cotton media. And always refer to your vehicle's manual and K&N's warranty terms for any specific instructions or limitations.
