Using this intake kit is straightforward. First, make sure your engine is cool before starting the installation. You can typically install the entire system in less than 60 minutes. Just follow the included instructions step - by - step. When driving, under normal highway conditions, you won't need to service the filter until you've hit 100,000 miles. But if you drive in dusty or dirty environments, check the filter more often. To clean the filter, simply wash it with the appropriate cleaning solution and let it dry. Then, re - oil it before reinstalling. Remember, in California, some intakes are not legal for use on pollution - controlled vehicles, so always check the CARB status for your specific vehicle in the product specifications.
