aFe Silverado Sierra LML Stage-2 Pro DRY S Intake

GM LML Duramax Stage-2 intake details

aFe 54-13016D is the Magnum FORCE Stage-2 Pro DRY S intake for qualified 2011-2016 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD trucks with the 6.6L LML Duramax turbo diesel. One nine-inch three-layer oil-free synthetic filter fits an open molded XLPE housing and molded tube. Transfer the original MAF, humidity sensor when equipped, filter minder and retained mounting pieces. The linked exact shared manual lists 21-91120 for the dry kit; exact-part retailer replacement references differ, so current replacement-filter identity and flange revision require confirmation.

Key Features

• One Pro DRY S filter, with three-layer oil-free synthetic media; shared manual lists alternative filters rather than two supplied filters.
• Molded XLPE open housing and intake tube; no generic metal heat-shield construction is substituted.
• Silicone bellows coupling and two supplied #072 clamps connect the tube to the turbo inlet.
• Transfers MAF and optional humidity sensor; block-off plate, foam gasket and socket-head screws address the absent humidity sensor.
• Transfers the original filter minder using its original grommet and retains the factory housing bottom plug.
• Two distinct trim seals: 37.5-inch double-bulb top seal and 26-inch side seal; no cutting or modifications stated.

Fitment

The exact shared manufacturer manual explicitly covers 2011-2016 Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD and Sierra 3500 HD with the 6.6L turbo diesel; current oiled-page application identifies LML. Preserve every original named-trim row, shorter range and compressed fitment tag. Exact selected-part retailer tables restore missing Silverado 3500 HD LT 2011-2016 and Sierra 2500 HD WT 2011-2014. Named Base and High Country ranges remain 2015-2016; existing Sierra 3500 HD WT stays 2011-2014. Sensor equipment varies: earlier LML installations may lack humidity sensing. Match actual sensors, filter-minder port, mounting and filter/housing revision; no gasoline engine, earlier Duramax generation or 2017-on L5P fitment is inferred.

Verify 54-13016D against the actual engine, sensor and vent connections, mounting locations and applicable emissions requirements before ordering.

Specifications

What's Included

This table transcribes the exact shared linked-manual bill with the filter conflict explicitly identified; it does not certify interchangeable filter revisions. The current oiled product page links 24-91154 and describes a six-inch flange, while the shared manual lists 24/21-91120. Dry replacement references require manufacturer confirmation. The manual step for an absent filter minder calls item K a grommet, but K in the bill is the bellows coupling; do not treat this as a separately verified grommet part or invent a service number. Retain original MAF, optional humidity sensor, filter minder and its factory grommet, original bottom retaining plug and factory mounting grommets. Alternative-media filter is not a second included filter.

Frequently Asked Questions

One Pro DRY S three-layer oil-free synthetic filter. The other filter in the shared bill is an alternative, not a second included element.

The linked exact shared manual lists 21-91120 for the dry kit; exact-part retailer replacement references differ, so current replacement-filter identity and flange revision require confirmation.

No. The manual notes that earlier models may have only the MAF. Transfer the original humidity sensor if present, or fit the supplied gasket, block-off plate and socket-head screws.

No new minder is itemized. Transfer the original minder using its original grommet. For an absent minder, the manual's item-K grommet reference conflicts with its bill and needs revision confirmation.

Move the bottom retaining plug from the original housing to the new housing and seat the assembly firmly in the factory mounting grommets.

Install the shorter 26-inch bulb seal on the side and the longer 37.5-inch double-bulb seal around the top, following the illustrations.

Fit the bellows to the turbo inlet first. Seat the tube in the filter, then into the bellows, align and tighten all clamps before reconnecting sensor harnesses.

The shared chart labels selected media at 600 versus 440 CFM stock at 7 inches H2O. The shared flow chart explicitly identifies dry media, but the linked dyno run is labeled Magnum Force Pro 5R. Its results are not a dry-media certification. An independent dry-media dyno chart was not located. The linked dyno uses modified exhaust/intercooler and different run dates/SAE factors. Recheck screws, clamps and connectors after 100-200 miles; no numeric torque is given. Non-CARB restrictions remain applicable.

Installation Instructions

Verify aFe 54-13016D. Read the complete manual and work on a cool engine. Disconnect the MAF and humidity-sensor plugs if equipped, loosen tube clamps and lift out the original tube and airbox. Install the selected filter in the new housing from above and lock its lip through the round opening. Install the shorter seal on the side and longer seal around the top. Transfer the original MAF and humidity sensor if equipped using supplied M4 Torx hardware. If humidity sensing is absent, install the supplied foam gasket, block-off plate and socket-head screws in that position. Transfer the original filter minder with its factory grommet; for an absent minder, resolve the manual's contradictory grommet callout and verify a secure sealed port before use. Transfer the original bottom retaining plug to the new housing and seat the housing firmly in the factory mounting grommets. Place the filter clamp over its flange without tightening. Fit the bellows to the turbo inlet and secure one supplied clamp, leaving the other end clamp loose. Seat the tube in the filter first, then in the turbo-inlet coupling; align and tighten all clamps. Reconnect the original MAF and humidity harnesses if equipped, verify all components are secure and recheck screws, clamps and connectors after 100-200 miles. No battery-disconnection step or numeric torque is specified in this exact manual.

Important Disclosures

The current exact oiled manufacturer page, its linked sixteen-page shared manual naming both selected media, all four contact sheets, complete bill and Figures A-I were read and visually inspected. A current standalone dry product page was not located; dry identity and installation are supported by the exact shared primary manual, with secondary dry-media descriptions qualified. The manual and current page conflict on replacement filter/flange, and the absent-minder step has an inconsistent item-K callout; no unverified substitute part is certified. The shared flow chart explicitly labels Pro 5R 630, dry 600 and stock 440 CFM at 7 inches H2O; selected improvement is approximately 36.36%. The shared flow chart explicitly identifies dry media, but the linked dyno run is labeled Magnum Force Pro 5R. Its results are not a dry-media certification. An independent dry-media dyno chart was not located. The actual linked dyno compares a 2011 Chevy 2500 LML baseline April 7, 2021 at 7:45:57 a.m., SAE 1.00, with Pro 5R July 15, 2021 at 12:49:28 p.m., SAE 1.03. Both run notes list aFe BladeRunner intercooler 46-20111, aFe five-inch DPF-back exhaust 49-44041-B, fourth gear, 40% load and Linx not connected; RPM is SW-defined. Baseline title Refone Turbocharger is not proof of an otherwise stock powertrain. Run dates and correction factors differ; actual weather is not supplied. Marked-point gains and differences between separate maxima are not interchangeable. No guaranteed output, fuel-economy or delivered-price claim is made. Exact Turn14 data remains unavailable without authenticated access. Protected commercial data and price are unchanged.
