Airbox Flanges helps to secure the duct to the air box in a cold air kit. A cold air kit comes with air box flange, flange template, duct, inlet port, hose clamps and fasteners. The cool power air intake system provides additional cold air to the stock sealed air box through a PSM duct located beneath the air box. Cold air is picked up as the air passes under the vehicle. Air enters an inlet port located behind the bumper at the bottom of the stock vertical air baffle.
