Using this intake kit is straightforward. First, make sure your vehicle is turned off and cooled down. It usually takes less than an hour to install the whole system. Simply follow the included instructions. When it comes to maintenance, under normal highway driving, you can go up to 100,000 miles before servicing the filter. The filter is washable and reusable, so you can clean it and re - oil it to keep it performing well. Remember, if you're in California, check the CARB status of each part for your specific vehicle as some intakes may not be legal for use on pollution - controlled vehicles.
