aFe Quantum Pro 5R Cold Air Intake System 11-16 GM/Chevy Duramax V8-6.

Quantum Cold Air Intake Systems (Patent Pending) by aFe POWER are the latest in airflow technology for your GM Duramax 6.6L (td) truck. From the uniquely integrated filter-to-housing design to the state of the art, lightweight injection molded base and top Pro 5R filter, Quantum delivers dyno-proven performance gains, convenience, value and installs in minutes.

Unique Integrated Filter-to-Housing Intake Design:
Quantum uses an integrated filter-to-housing design by attaching both components with four captive screws for a positive surface area seal and quick and easy install. Quantum's roto-molded housing features a unique, five rib industrial grade look for long lasting durability and aFe quality recognition.

Quantum Pro 5R Performance Air Filter:
This system is equipped with our oiled, 360-degree radial flow air filter with five layers of progressive, cotton media to provide maximum flow, performance and protection. Specifically designed for the Quantum Series intake systems, the air filter features an injection molded base and top for lighter weight and rigidity. Captive screws are used to eliminate lost hardware and to securely fasten to the housing. The base includes a built-in, 3-angle velocity stack for smooth, even airflow. Inverted top filters offer more surface area for longer life and an exceptional look.

Dyno Tuned Intake Tube:
Quantum uses a dyno tuned, CAD-designed intake tube to achieve optimum air flow. It's made from high impact, XLPE material for heat soak resistance and durability while maintaining a perfect fit.

Silicone Bellows Coupling:
The Quantum Intake System includes a silicone bellows coupling to absorb excessive engine movement and provide flexibility for a secure and easy install. Quantum intakes are designed with fewer parts for a quick and simple installation.

Hassle-Free Installation:
This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All clamps, couplings and hardware are included for a hassle-free installation.
