Using your K&N air filter is a breeze. First, locate your factory air box. Open it up and carefully remove the old air filter. Then, simply place the K&N filter in the same spot. Make sure it fits snugly and close the air box. As for maintenance, check the filter regularly, especially if you drive in dusty or dirty conditions. When it looks dirty, it's time to clean it. You can use a K&N filter cleaning kit. Just follow the instructions on the kit to wash and re - oil the filter. Avoid using harsh chemicals or excessive force when cleaning. And always remember, this filter is designed to last a long time, so with proper care, you won't have to replace it often.
