Using your K&N air filter is easy. Just take out your old filter from the factory air box and drop this new one in. It's designed to fit right in without any hassle. When it comes to maintenance, every 50,000 - 100,000 miles, depending on your driving conditions, you'll want to clean it. You can use K&N's special cleaning kit. First, gently tap the filter to get rid of big dirt pieces. Then, soak it in the cleaner as per the instructions on the kit. Rinse it carefully with water and let it dry completely. After that, re - oil it with K&N filter oil. As for storage, keep it in a dry place away from direct sunlight. Also, always make sure the filter is properly installed to avoid any air leaks that could affect your engine's performance.
