GMC Sierra 3500HD Performance Air Intake - aFe - Magnum FORCE Stage-2XP w/ Pro 5R Filter - `17-`19. A direct-fit cold air intake system designed for the 6.6L L5P diesel that replaces the factory intake with a high-flow, washable Pro 5R filter and a durable XLPE housing.
The Stage-2XP pairs a 9" 360-degree radial-flow Pro 5R filter (pre-oiled, five-layer cotton gauze) with a computer-designed, dyno-tuned intake tube and an open-element XLPE polymer housing that resists heat soak. The inverted-top filter increases surface area for longer service intervals, while the open housing showcases the filter and produces a more aggressive intake sound under load. This system uses the OE air inlet, installs in factory mounting locations with no cutting or modification, and includes all clamps and hardware for a straightforward install—roughly 15 minutes on many trucks. Dyno-proven results and flow figures from the manufacturer are included for reference.
