Using this intake kit is quite straightforward. First, make sure your engine is cool. Then, follow the included instructions to install the kit, which usually takes less than an hour. During normal use, under highway driving conditions, you can go up to 100,000 miles before servicing the filter. However, if you drive in dusty or dirty environments, you may need to service it more often. To service the filter, simply remove it, wash it with the recommended cleaner, and let it dry before reapplying the oil. Also, remember that in California, some of these intakes may not be legal for use on pollution - controlled vehicles, so always check the CARB status before installation.
