Using this K&N intake kit is easy. First, make sure your engine is cool before starting the installation. Follow the included instructions, and you can typically have it installed in less than an hour. When it comes to maintenance, under normal highway driving, you can go up to 100,000 miles before servicing the filter. Just clean the washable, reusable High - Flow Air Filter using the recommended cleaning solution. Remember, if you're in California, check the CARB status of the part for your vehicle as some intakes aren't legal for pollution - controlled vehicles.
