Using your K&N air filter is super easy. First, open your vehicle's factory air box. Then, simply remove the old air filter and drop in the new K&N filter. Make sure it fits snugly. When it comes to maintenance, every 50,000 - 100,000 miles (depending on your driving conditions), you'll need to clean the filter. Use K&N's special cleaning kit. Just soak the filter in the cleaner, rinse it gently, and let it dry completely. After that, apply the K&N filter oil evenly. As for storage, keep it in a dry place. And remember, this filter is made to last a long time, but if you have any issues, K&N's 10 - Year/Million Mile Limited Warranty has you covered.
