aFe 51-32642-1B is the Rapid Induction Pro DRY S intake for qualified Ford F-150 EcoBoost applications. One oil-free filter, molded branched tube and top-mounted heat shield retain the original lower airbox and IAT. Current primary identifies 2.7L 2015-2026 and 3.5L 2015-2016; the exact manual ends 2.7L cover at 2024. The vent insert is explicitly for the specified 3.5L arrangement only.
Current exact dry primary identifies F-150 2.7L EcoBoost 2015-2026 and 3.5L EcoBoost 2015-2016. Its sixteen-page manual ends 2.7L cover at 2024, while retaining the same 3.5L years. Exact selected dry Mont Motorsports table supports eight named groups: King Ranch/Platinum 2015-2016, Limited/SSV 2016, Lariat 2015-2023, STX 2024-2026 and XL/XLT 2015-2026. Earlier luxury and SSV rows require the actual qualified 3.5L engine where 2.7L was not offered. The original model-only 2015-2021 row remains conditional on those engine/year limits. No later 3.5L, PowerBoost or Raptor fit is inferred. Later primary 2.7L coverage does not establish a revised procedure or later emissions exemption.

The shared-bill oiled filter is a separate configuration, not a second supplied filter. Original lower airbox, clips and tabs, IAT and original turbo-inlet/vent arrangements remain. No new MAF, IAT extension harness, cover or lower airbox is listed. The 3.5L vent procedure leaves valve-cover connection and sensor/harness attached and is performed with original turbo-inlet tubes installed. It is explicitly unnecessary for 2.7L. The current manual names aluminum sensor adaptor and M6 x 1 x 25 screws; different kit materials and unspecified lengths are not transferred. Primary heat-shield gauge differs from older retailer copy, so actual supplied revision remains qualified.
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 21-91040 Pro DRY S oil-free filter with three synthetic layers, 5.5-inch flange and 5.75-inch height.
Does this replace the entire original airbox?The upper assembly is replaced; original lower airbox, tabs and retaining clips remain in use.
Which screws secure tube to shield?Two M6 x 1 x 25 screws with two flat washers and two lock washers are listed.
How does the IAT lock?Turn it clockwise a quarter-turn into the manual-specified aluminum adaptor and ensure its tab clips over the ramp.
Does the 2.7L use the supplied vent insert?No. The exact manual limits that directional insert procedure to the specified 3.5L arrangement.
Must the valve-cover end or its sensor be removed?No. Release only the turbo-inlet end, leave the valve-cover connection attached and protect the existing sensor and harness.
Does later 2.7L fitment establish later emissions exemption?No. Match the exact order, application and engine family; later manufacturer fitment does not extend the reviewed exemption evidence.
What battery, torque and follow-up instructions apply?There is no mandatory battery-disconnection step or numeric torque. Retighten connections after approximately 100-200 miles; optional code clearing may reset radio presets.
Verify aFe 51-32642-1B. Read all sixteen pages and figures A-D and F-K. Work on a cool engine ; the current manual gives no mandatory battery-disconnection step. Turn original temperature sensor counterclockwise a quarter-turn and remove it. Loosen three original tube clamps and remove tube, upper airbox and filter while retaining lower airbox. Fit supplied grommet and aluminum sensor adaptor to new tube. Loosely fit both couplings and all four clamps. Attach tube to shield using two M6 x 1 x 25 screws, lock washers and flat washers. Fit selected filter with its flat edge aligned to top of airbox, tighten its clamp and install trim seal. Lower complete assembly by lining up original airbox tabs before couplings, then close original airbox clips. Turn original IAT clockwise a quarter-turn into adaptor and ensure its plastic tab clips over the fitting ramp. Tighten clamps and screws. For the specified 3.5L only, with original turbo-inlet tubes installed, locate the driver-side inlet and valve-cover vent connection. Release vent tube only at turbo-inlet end; leave valve-cover connection, sensor and harness attached. Insert supplied vent piece with slash cut toward turbo, fully seated against shoulder; it must not be loose or rotate. Reconnect vent fitting until it snaps and tug-check retention. The vent-insert steps are not necessary on 2.7L. No numeric torque is specified; retighten all connections after approximately 100-200 miles. Final code-clearing note mentions code reader or battery reset and radio preset loss; it is not a supplied tune or mandatory battery-disconnection procedure.
Current exact dry primary advertises 84 percent more flow without a linked airflow or dyno chart. No unseen original baseline, test pressure, horsepower or torque result is reconstructed, and the different later-family flowchart is not borrowed. Current Rapid Induction naming differs from older MagnumFORCE Stage-2 labeling, while the exact linked manual identifies this selected suffix part. Primary 2.7L coverage extends through 2026 versus manual 2024; both limit 3.5L to 2015-2016. Primary heat-shield thickness is 18 gauge while older exact retailer copy says 16; actual supplied revision remains qualified. Current primary references D-550-28 for some applications. Older exact manuals restrict their exemption wording to 2015-2016, and indexed official evidence names this selected part, but the complete current official order remains unverified and the prior access challenge is not retried. Physical fitment through later years is not blanket emissions exemption. Existing exact EO metadata is preserved with those limits.
