aFe 54-11872-1 is the Magnum Force Stage-2 Pro 5R open-element intake for the 2011-2016 Ford Super Duty 6.7L Power Stroke diesel. The exact shared manual names F-250, F-350 and F-450. One blue oiled filter, XLPE housing and tube replace the original intake assembly while transferring the original MAF, inlet gasket, mounting grommet and sleeve. The manual includes specific coolant-tube retention for 2015-2016.
Current primary specifies Ford diesel trucks 2011-2016, 6.7L. The exact full manual names Super Duty F-250, F-350 and F-450 for those years. The original broad F-250 and F-350 2011-2016 rows remain unchanged. Ten genuine named groups are restored from the exact ML Performance North American table: King Ranch, Lariat, XL and XLT 2011-2016 plus Platinum 2013-2016 for each F-250 Super Duty and F-350 Super Duty. One model-only F-450 Super Duty 2011-2016 row is restored from the manual, without inventing Base or individual trim coverage. All rows require actual 6.7L diesel and the illustrated sensor, inlet gasket, mounting and coolant-hose arrangement. F-550 appears in exact retailer results but is absent from the manual cover; exact housing/configuration proof remains held, not declared physically incompatible. Indexed MVP named F-450 rows differ from the current full page’s All rows, so no new individual F-450 trims are asserted. No gasoline, later truck or cab/chassis subtype is inferred. D-550-24 exact exemption scope remains held; manufacturer says some or all applications, not all listed vehicles.

One selected oiled filter is supplied; the shared bill’s dry and gold filters are alternatives. Reuse the original MAF, front inlet gasket, mounting grommet/sleeve and original airbox mounting bolt. No replacement sensor, new battery-side grommet, coolant hose, tuning module, prefilter or restore kit is included. Parts pictured in the manual accessory page are separate purchases.

Which applications does the manual name?2011-2016 Super Duty F-250, F-350 and F-450 with the 6.7L turbo diesel. Exact F-550 housing/configuration proof and individual F-450 trim differences remain held.
What changes on 2015-2016?Cut the original coolant-tube tie during removal and install the supplied replacement tie after assembly. Retain the molded tube-hook seating for the coolant tube.
Which factory seals and mounts transfer?The front inlet rubber gasket and battery-side mounting grommet with its metal sleeve transfer to the new housing. Reuse the original airbox mounting bolt.
How does the MAF transfer?Use the supplied gasket, two nylon spacers and M4 Torx screws. Reconnect until the plug clicks, then press the red lock in.
How are the turbo and filter connections seated?Install turbo adaptor radius edge outward, keep the oval tube end over it, slide bellows onto the filter adaptor and seat the filter flange against the housing wall.
What do the actual charts show?Selected-media bench flow is 750 versus 480 CFM at 7 inches H2O. Marked dyno differences are 18.32 hp and 35.04 lb-ft; peak differences are 18.28 hp and 11.29 lb-ft, with incomplete run conditions.
What battery, torque and recheck instructions apply?Disconnect both negative battery terminals and reconnect both after assembly. No numeric torque is printed. Retighten connections after approximately 100-200 miles.
Verify aFe 54-11872-1. Read all 16 pages, work with a cool engine and disconnect BOTH negative battery terminals. Remove the two original intake/airbox screws and loosen clamps; cut the original coolant-tube tie on 2015-2016 only. Release the harness clip, pull out the sensor connector red lock, unplug and remove the original MAF using the supplied T20 bit. Pull the airbox up and retain its front inlet gasket and battery-side grommet/sleeve. Move hoses aside and remove the original tube. Transfer MAF with gasket, nylon spacers and supplied sensor screws. Place the largest clamp at the oval tube end, fit bellows and clamps to the small end and slide flush without tightening. Transfer original grommet/sleeve and inlet gasket to the new housing. Fit trim, then adaptor with five screws and wavy washers. Fit turbo adaptor with radius edge outward and loosely install the tube over it. Fit the housing using its original mounting bolt. Slide bellows back onto the filter adaptor, align and tighten clamps while retaining oval-end seating. Snap coolant tube into the molded hook recess. Install filter with its flange contacting the housing wall. Reconnect MAF until it clicks and press in the red lock. Secure hoses with the 3/4-inch fixing clamp, washer and M6x1x20 screw, and replace the coolant-tube tie on 2015-2016. Check all components and reconnect both batteries. Retighten connections after approximately 100-200 miles. No numeric torque is supplied. Apply the matching EO label only to its exempt application.
Exact current primary, all 16 manual pages, all four page contacts, complete A1/A2/A3/B-S bill and figures A-I/K, plus actual linked bench-flow and dyno charts were reviewed. Actual primary and bill specify XLPE housing/tube, correcting generic metal top-half shield copy. Bench flow at 7 inches H2O is Pro 5R 750, stock 480, Pro DRY S 695 and Pro GUARD 7 690 CFM; only 750 versus 480 belongs to selected-media comparison. Dyno marked 2750-rpm values are 318.73 versus 300.41 hp and 608.95 versus 573.91 lb-ft, differences 18.32 and 35.04. Chart peaks are 319.59 versus 301.31 hp and 649.75 versus 638.46 lb-ft, differences 18.28 and 11.29; advertised 35 lb-ft is not the peak-to-peak difference. The chart states SAE smoothing 5 but does not establish vehicle, dates, media configuration and matched environmental run conditions, so no guaranteed road result is claimed. D-550-24 full scope remains held after prior challenge; no access retry or blanket later-year exemption. Ten exact named groups and the manual-supported F-450 model row are restored; original broad rows and bounds preserved. F-550 positive retailer coverage and individual F-450 trim/source differences remain explicit follow-up holds. Turn14 authenticated access remains unavailable. Prices, media and protected commercial data remain unchanged.
