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. These systems are paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 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.

K&N industrial strength degreaser helps dissolve dirt, old filter oil, and other filter-clogging particulates, allowing them to be rinsed away easily with water. When used as directed, the included air filter oil remains suspended in the pleats of the cotton filter material, allowing for exceptional contaminant capture. Available as complete cleaning kits or various sizes of individual cleaner and oils.
