Using this intake kit is easy. First, gather all the tools needed for installation. You can usually install the whole system in under an hour. Just follow the step - by - step instructions provided. When it comes to the air filter, under normal highway driving, you can go up to 100,000 miles before needing to service it. But keep an eye on it and if you notice reduced performance or a dirty filter, clean it. To clean the filter, use a special cleaning solution and let it dry completely before reinstalling. Also, remember that in California, some intakes may not be legal for use on pollution - controlled vehicles. Always check the product specifications for the CARB status of each part for your specific Jeep Wrangler model.
