Using your K&N air filter is easy. First, open your vehicle's factory air box. Then, take out the old air filter and replace it with the K&N filter. Make sure it fits snugly. When it comes to maintenance, check the filter regularly, especially if you drive in dusty or dirty conditions. You can wash it with a K&N filter cleaner when it gets dirty. Let it dry completely before applying the filter oil provided. Remember, don't use any other type of oil as it may damage the filter. Store the filter in a clean and dry place when not in use. If you have any questions, K&N's customer service is there to help.
