Using your K&N Typhoon air intake system is easy. First, make sure your vehicle is turned off and cooled down. Then, carefully install the intake system following the included instructions. Start by removing the old air intake components and then attach the new K&N system in their place. When it comes to maintenance, every 50,000 miles or so, clean the High - Flow Air Filter. You can use a K&N filter cleaning kit to wash the filter. After washing, let it dry completely before applying the filter oil. Remember, in California, some intakes are not legal for use on pollution - controlled vehicles, so always check the CARB status before installing the product on your car.
