Using your K&N air filter is easy. First, open your vehicle's factory air box. Take out the old air filter and replace it with the K&N filter. Make sure it fits snugly in place. When it comes to maintenance, check the filter regularly for dirt and debris. If it looks dirty, it's time to clean it. To clean, use a K&N filter cleaning kit. Follow the instructions on the kit to wash the filter gently with the provided cleaner. Rinse it thoroughly and let it dry completely before re - oiling it with the K&N filter oil. Always use genuine K&N products for cleaning and oiling to keep the filter performing at its best. Remember, avoid using harsh chemicals or rough scrubbing as it can damage the filter.
