Using this K&N air filter is a breeze. First, open your vehicle's factory air box. Carefully remove the old air filter and place the K&N replacement filter in its spot. Make sure it fits snugly. When it comes to maintenance, every 50,000 to 100,000 miles, depending on your driving conditions, you'll want to clean the filter. Use K&N's recommended cleaning kit. Just soak the filter in the cleaning solution, rinse it gently, and let it dry completely before applying the filter oil. Be careful not to over - oil the filter as it can cause issues with your vehicle's sensors. Also, always refer to your vehicle's manual if you're unsure about anything. This way, your filter will keep performing at its best and last for the life of your vehicle.
