An enclosed air box design helps protect the filter and inlet air from the heat of the engine bay, and the air box lid allows for quick and easy access to the filter without tools. 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 of the filter allows you to go up to 100,000 miles between filter services under normal highway driving conditions. The system can typically be installed in less than 60 minutes.
K&N’s enclosed air box roto-molded cold air intake systems are guaranteed to provide an increase in horsepower and torque, and are protected by the K&N No-Hassle Lifetime Limited Warranty.
