Construction & Design

The intake system’s core component is a rotationally molded HDPE tube, chosen for its strength, heat resistance, and smooth internal surface that promotes laminar airflow. This material helps maximize the volume of cool air delivered to the engine, improving combustion efficiency. The custom NextGen air box is engineered to isolate the intake air from the high temperatures of the engine bay, ensuring cooler, denser air reaches the combustion chamber.

The DryFlow air filter features a synthetic, oil-free media that provides excellent filtration while eliminating the mess and hassle associated with traditional oiled filters. Its oversized, conical shape increases surface area for airflow and dirt-holding capacity, extending service intervals and maintaining consistent performance over time.

Performance & Sound

By increasing airflow by over 36%, this cold air intake system delivers a noticeable boost in engine power, with gains of 14.3 horsepower and 15.1 lb-ft of torque. These improvements translate to enhanced throttle response, better acceleration, and a more engaging driving experience. The intake also produces a subtle, aggressive induction sound that enhances the driving experience without being intrusive.
