Using this intake kit is easy. First, make sure your engine is cool before starting the installation. It usually takes less than an hour to install the whole system. Once installed, enjoy the improved performance of your vehicle. For maintenance, under normal highway driving, you can go up to 100,000 miles before servicing the filter. When it's time for a service, simply wash the reusable High - Flow Air Filter with the appropriate cleaning solution and re - oil it. Keep an eye on the heat shield to ensure it's protecting the intake air from the engine's high temperature. Remember, in California, some intakes aren't legal for pollution - controlled vehicles, so always check the CARB status for your specific part and vehicle model.
