Using your K&N air filter is easy. First, make sure your motorcycle engine is cool. Locate the air filter housing and carefully remove the old filter. Then, insert the new K&N filter in place of the old one, ensuring it fits snugly. Close the air filter housing securely. When it comes to maintenance, it's a good idea to check the filter regularly, especially if you ride in dusty or dirty conditions. You can clean the filter using a K&N filter cleaning kit. Just follow the instructions on the kit. As for storage, keep the filter in a dry and clean place. And remember, always refer to your motorcycle's manual for any specific instructions related to your model.
