aFe 51-72005 is the Momentum HD oil-free intake for qualified 2013-2018 Ram 6.7L Cummins trucks. One 21-91059 filter uses three synthetic layers and 9-inch height. The original Ram Active Air motor, flap, mounting screws, MAF and temperature sensor transfer to the molded housing and tube; those original components are required.
Current exact dry primary identifies Ram diesel trucks 2013-2018 with 6.7L Cummins. Its linked sixteen-page manual explicitly identifies Ram 2500, 3500, 4500 and 5500 for those years. Two model-level 4500/5500 groups are restored directly from that exact manual without invented trims. Exact dry retailer tables restore 2500 ST 2013 and 3500 SLT 2013-2018. All original named ranges and the separate 3500 Lone Star 2017 row remain, including its 2016 gap. Actual sensor, Ram Active Air, vent and mounting arrangement must match; no gas HEMI, earlier system or later truck is inferred. Physical fitment is separate from the narrower reviewed emissions order.

Shared-bill oiled elements are alternatives, not additional supplied filters. The exact bill does not list a new MAF, temperature sensor, Ram Active Air motor/flap, factory mounting grommets or optional auxiliary plug. Those original sensors, active-valve mechanism and wiring, original T30 mounting screws, housing retention screw and engine-side crankcase clamp are reused. Do not add a cleaner or the different -E package contents. Older retailer auxiliary-plug, coupling-ply and efficiency wording conflicts with the actual current manual or primary; confirm actual supplied revision rather than combining bills.
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
One 21-91059 Pro DRY S oil-free filter with three synthetic layers and 9-inch height.
Is the Ram Active Air valve supplied new?The original motor and flap transfer using original T30 screws; ensure the flap is fully engaged on its shaft and reconnect its wiring.
Which sensors transfer?Both original MAF and temperature sensors transfer to the new tube using three supplied M4 screws.
Which crankcase clamp is reused?The original engine-side clamp is reused; the supplied mini clamp secures the new hose at the intake-tube end.
Which connection goes first?The assembled coupling slides over the turbo first, then the tube connects to the filter.
Are a cleaner and auxiliary plug included?Neither is listed in this exact bill. Do not combine contents from retailer generic copy or the different -E package.
Does the reviewed EO cover every manual application?Its selected row identifies 2013-2017 2500/3500 pickups and 3500 cab chassis, without establishing 2018 or 4500/5500 exemption.
What battery, torque and follow-up instructions apply?Disconnect and later reconnect both batteries. No numeric torque is specified; verify all connections after 100-200 miles.
Verify aFe 51-72005. Read all sixteen pages and figures A-I. Work on a cool engine and disconnect negative cables at BOTH batteries. Remove original housing retention screw and disconnect MAF and temperature harnesses. Release original crankcase line, retaining its clamp, and loosen turbo connection. Lift original system only far enough to reach and disconnect Ram Active Air wiring before removal. Open housing, disconnect flap ball joint, remove original T30 screws and separate flap from motor shaft as illustrated. Transfer motor and flap to new housing, firmly engage flap on shaft and secure with original screws. Fit selected filter and larger housing/filter clamps loosely. Reconnect active-valve harness, seat housing firmly in original grommets and loosely reinstall original retention screw. Transfer both sensors using three furnished M4 screws. Fit supplied vent hose to tube, tighten supplied mini clamp on that end and place original clamp on its other end. Loosely fit coupling and two smaller T-bolt clamps on tube. Install coupling onto TURBO FIRST, then connect tube to filter. Align assembly and tighten clamps and screws. Reconnect vent hose to original crankcase line with original clamp, reconnect both sensor harnesses and both batteries. Verify all connections and recheck after 100-200 miles. No numeric torque is specified. Apply EO label only to the exact eligible application.
Current exact dry primary advertises 58 percent more flow without linking a flowchart; no unseen original baseline or selected-media pressure is reconstructed. Its linked 2013 Ram 2500 dyno explicitly identifies the oiled 50-series intake and is not independent selected dry-media certification. Marked differences near 2120 rpm are 7.16 hp and 18.02 lb-ft; run maxima differ by only 0.12 hp and 13.08 lb-ft. Baseline May 27 and intake July 1, 2014 use STD 1.06 correction, original exhaust, fourth gear and 40-percent brake with different weather and dates. Current manual explicitly includes 4500/5500 and 2018, while the full cached official D-550-26 and rendered Exhibit A identify the selected family for 2013-2017 2500/3500 pickup and 3500 cab chassis. That order does not establish 2018 or 4500/5500 exemption. Existing exact EO metadata is retained with this limitation; no blanket 50-state claim is made. No oiled-filter 1,000-CFM or efficiency value is transferred to this selected dry system.
