Using your Injen air filter is easy. Just install it in your engine's air intake system according to the vehicle's manual. To keep it in top shape, clean it regularly using the Pro Tech air filter cleaning kit (part number X - 1030). When cleaning, make sure to follow the instructions on the kit carefully. Avoid using harsh chemicals or abrasive materials as they can damage the filter. Check the filter periodically for any signs of excessive dirt or damage. If you notice significant wear or a large amount of dirt that can't be removed by cleaning, it might be time to replace the filter. Remember, a well - maintained air filter will ensure your engine runs smoothly and efficiently.
