Using this intake kit is easy. First, make sure your engine is cool. Follow the step - by - step installation guide that comes with the kit, and you can usually have it installed in less than an hour. When driving under normal highway conditions, you won't need to service the filter until you've driven up to 100,000 miles. Just keep an eye on your engine performance. If you notice a drop in power, it might be time to check the filter. To clean the filter, use a K&N filter cleaning kit as directed. Remember, some intakes are not legal for use on pollution - controlled vehicles in California, so always check the CARB status for your specific vehicle before installation.
