Using your K&N universal air filter is easy. Just find the right spot in your equipment's air intake system and attach the filter securely using the pliable rubber flanges. Make sure it's properly seated to ensure optimal airflow. When it comes to maintenance, keep an eye on the filter's dirt level. Once it gets dirty, you can wash it. Use a mild cleaner and warm water, then let it dry completely before reinstalling. As for storage, keep it in a dry place. Avoid using sharp objects on the filter, as this could damage it. Also, make sure to check the fit regularly, especially if you notice a change in your equipment's performance.
