The 63-1581 cold air intake system is engineered specifically for 2012-2018 Jeep Wrangler JK V6 3.6L models. A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. The system includes a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media, and the oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. An enclosed air box design helps protect the filter and inlet air from the heat of the engine bay, and includes a foam pre-filter for additional air flow and engine protection in very dirty conditions. The entire system can typically be installed in less than 90 minutes. Some intakes are not legal for sale or use on any pollution controlled motor vehicle in California. See the product specifications for CARB status on each part for a specific vehicle.
