aFe 51-73112-1 is the Momentum GT Pro DRY S intake for qualified F-150 EcoBoost applications. One 21-91092 filter uses three oil-free synthetic layers and 9-inch height. Current manufacturer scope is 2.7L 2015-2026 and 3.5L 2015-2016; the exact manual ends its 2.7L cover at 2024. The original IAT transfers, and the directional vent insert is for the specified 3.5L arrangement only.
Current exact dry manufacturer page identifies F-150 2.7L twin-turbo 2015-2026 and 3.5L twin-turbo 2015-2016. The exact suffix manual ends its 2.7L cover at 2024; later primary coverage does not establish a revised procedure. Exact dry Mont Motorsports named table supports XL/XLT 2015-2026, STX 2024-2026, Lariat 2015-2023, King Ranch/Platinum 2015-2016 and Limited/SSV 2016. Those eight groups are restored with actual engine/year qualification. Early luxury and SSV rows require the actual 3.5L configuration where 2.7L was not offered; no engine pseudo-trim is created. The original model-only 2015-2021 row remains unchanged and conditional on the actual documented engine/year combination. No later 3.5L, PowerBoost or Raptor coverage is inferred.

The exact suffix manual lists oiled and Pro-GUARD filters as alternative media, not additional included elements. Original IAT, mounting grommet, housing screw and harness clips transfer. No new MAF, controller or extension harness is itemized. Unlike the later 3.5L Momentum GT procedure, this manual routes original sensor wiring into existing small housing holes and does not direct optional quarter-inch drilling or wastegate-controller transfer. Do not borrow those steps from the later family. The manual next-page prompt says vent procedure for 2016 models, while the bill and individual figures specify 3.5L only; confirm the actual 2015 arrangement before applying that subsection.
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 21-91092 Pro DRY S element with three oil-free synthetic layers and 9-inch height. Other shared-bill media are separate versions.
Do both engines share the same year range?No. Current primary lists 2.7L 2015-2026 but 3.5L only 2015-2016; the current exact manual ends its 2.7L cover at 2024.
Does the vent insert install on 2.7L?The exact bill and figures explicitly say it is not necessary on 2.7L. The vent subsection is for the specified 3.5L arrangement.
How does the IAT transfer?Remove it counterclockwise and lock it clockwise into the supplied aluminum fitting and grommet; restore the harness clips in the housing holes.
Does this manual require quarter-inch housing holes?No. Those optional holes belong to a later family procedure, not this exact suffix-manual routing.
Does the linked dyno independently test this dry suffix kit on 2.7L?It explicitly identifies earlier nonsuffix 54-73112 oiled intake on 2015 3.5L. It is qualified historical evidence, not an independent selected dry suffix or 2.7L test.
Does physical fit through 2026 mean exemption through 2026?No. The indexed selected-suffix EO rows identify 2016 2.7L/3.5L; later physical years do not establish exemption.
What torque and follow-up apply?No numeric torque is stated. Retighten connections after approximately 100-200 miles; battery disconnection is only an optional code-clearing method.
Verify aFe 51-73112-1. Read all sixteen pages and figures A-L on a cool engine. Rotate original IAT counterclockwise and remove it; release harness clip from airbox. Loosen all three original tube clamps, remove tube and retain original housing screw while removing two rivets and original housing. Transfer original housing grommet and fit edge trim. Seat new housing on original mounts, restore its original screw and fit both supplied rivets. Push in selected filter until locked. Fit supplied sensor grommet and aluminum fitting to new tube, then fit silicone couplings and clamps loosely. Slide couplings over original tubes first and new tube end into filter. Align and tighten clamps. Lock original IAT clockwise into aluminum fitting and restore harness clips in the housing holes. Check screws and clamps and remove window film. For the specified 3.5L vent arrangement only, keep original turbo-inlet tubes installed and release the driver-side inlet vent connector without removing its valve-cover end or damaging original sensor/harness. Fully seat insert with slash cut toward turbo inlet and ensure it cannot rotate. Reconnect and retention-check the vent fitting. This subsection is unnecessary on 2.7L; the manual 2016 prompt requires actual-configuration confirmation for 2015. Codes may be cleared by reader or optional battery disconnection; there is no general mandatory battery-removal step. No numeric torque is stated. Retighten connections after approximately 100-200 miles. Apply EO label only for an actually exempt configuration.
The exact dry page advertises 66 percent more flow without a linked comparison chart; no unseen baseline or pressure is reconstructed. Its linked dyno explicitly identifies earlier nonsuffix 54-73112 oiled intake on a 2015 3.5L. That does not independently certify this selected dry suffix version or 2.7L performance. Marked separate-rpm differences are 15.96 hp and 16.33 lb-ft; run maxima differ by 18.50 hp and 8.54 lb-ft. Both March 23, 2015 runs use SAE 1.01, original exhaust, third gear, Sport, 20-percent brake before run and tow off, at different times and weather. Advertised 17 lb-ft is not the exact marked difference. All sixteen manual pages were read and full bill viewed; bytes match the previously fully illustrated exact suffix manual, figures A-L. The vent section is explicitly unnecessary for 2.7L. A next-page prompt says 2016 models while individual figures specify 3.5L; confirm an actual 2015 vent configuration before using that subsection. Unlike later-family routing, this manual uses existing housing harness holes and gives no optional quarter-inch drilling or wastegate-controller transfer. Current primary 2.7L cover extends through 2026 while manual cover ends 2024; exact dry named tables support the separately restored later groups. D-550-28 selected-suffix indexed rows identify 2016 2.7L/3.5L only; earlier 2015 nonsuffix evidence is not selected-suffix exemption. Full official order remains a source hold and was not retried, and later physical fitment is not exemption. Existing exact EO metadata is preserved with this qualification.
