Using your K&N air filter is easy. First, locate your factory air box. Open it up, remove the old air filter, and simply drop in the K&N filter. Make sure it fits snugly in place before closing the air box. When it comes to maintenance, it's recommended to check the filter every 12,000 - 15,000 miles. If it looks dirty, you can wash it. Use a K&N filter cleaning kit. Soak the filter in the cleaner, rinse it gently, and let it dry completely. Then, re - oil the filter according to the kit's instructions. Remember to always follow the maintenance schedule to keep your engine running smoothly. Avoid using harsh chemicals or abrasive materials on the filter, as this can damage it. Also, make sure the filter is completely dry before reinstalling it to prevent any moisture from entering the engine.
