Is the fuel economy of your Jeep decreasing during the coldest weeks of winter and the hottest weeks of summer? Of course, that's usually due to the heater and air conditioning running. An air scoop for your Jeep cowl panel will maximize the efficiency of your Jeep's air circulation systems by increasing air flow while blocking dust and debris from clogging up the systems. You may see an increase in fuel economy as a result of increased efficiency. 4WD is proud to offer Rugged Ridge cowl scoops that come in chrome and "smoke." No drilling is required to install them, they adhere with automotive grade adhesive tape.
