Using your K&N air filter is a breeze. Just remove your old air filter from the factory air box and drop in the new K&N filter. Make sure it fits snugly. As for maintenance, it's recommended to clean and re - oil the filter every 50,000 to 100,000 miles, depending on your driving conditions. When cleaning, use a K&N filter cleaning kit. First, gently tap the filter to remove large debris. Then, soak it in the cleaning solution according to the kit's instructions. Rinse it thoroughly with water, let it dry completely, and re - oil it evenly. Avoid using sharp objects on the filter as it can damage the cotton media. And remember, this filter is backed by a 10 - Year/Million Mile Limited Warranty, so you can drive with peace of mind.
