Using the K&N air filter is easy. First, open your vehicle's factory air box. Carefully remove the old air filter. Then, place the K&N filter in the same position where the old one was. Make sure it fits snugly. Close the air box. That's it! For maintenance, you'll need to clean the filter regularly. Check it every few months or after a long dusty drive. If it looks dirty, wash it with a K&N filter cleaner. Rinse it gently with water and let it dry completely. Once dry, apply K&N filter oil evenly. This will help it capture contaminants effectively. When handling the filter, be gentle to avoid damaging the cotton media. And always use genuine K&N products for cleaning and oiling to ensure the best performance and warranty coverage.
