Description
The aFe POWER Quantum Cold Air Intake System with Pro 5R Filter represents the next generation of airflow technology for GM 6.6L Duramax diesel trucks. Designed with advanced CAD engineering and patent-pending features, the Quantum intake delivers dyno-proven performance gains, exceptional filtration, and easy installation, making it the ultimate upgrade for serious diesel enthusiasts.
Integrated Filter-to-Housing Design
The Quantum system features a unique integrated filter-to-housing interface, secured by four captive screws for a positive seal and effortless installation. The roto-molded XLPE housing is reinforced with five industrial-grade ribs for long-lasting durability and maintains a sleek, professional appearance in the engine bay.
Quantum Pro 5R Performance Air Filter
The included Pro 5R 360-degree radial flow filter uses five layers of progressive cotton media to deliver maximum airflow while maintaining superior filtration efficiency. The injection-molded base and top reduce weight and increase rigidity, while the inverted top design increases surface area for longer filter life. Built-in, 3-angle velocity stacks ensure smooth, even airflow for optimized engine performance.
Dyno-Tuned Intake Tube
The Quantum intake includes a CAD-designed, roto-molded XLPE intake tube that maximizes airflow while resisting heat soak. Its precision design ensures a perfect fit and optimal engine efficiency.
Silicone Bellows Coupling & Premium Hardware
A silicone bellows coupling absorbs engine movement while maintaining a secure connection, and included stainless steel clamps provide a leak-free, durable installation. The system’s design reduces parts for a fast and hassle-free installation.
