Using your K&N air filter is easy. 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, every 50,000 - 100,000 miles, depending on your driving conditions, you'll need to wash the filter. Use K&N's special filter cleaning kit, following the instructions on the kit. Let the filter dry completely before re - oiling it with K&N filter oil. Avoid using regular household cleaners or oils as they can damage the filter. When handling the filter, be gentle to prevent any tears in the cotton media. And remember, this filter is built to last, so you won't have to replace it as often as a regular filter.
