aFe 51-11872-1 is the Magnum Force Stage-2 Pro DRY S 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 grey oil-free 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 exact primary specifies Ford diesel trucks 2011-2016 with 6.7L engine; the full manual names Super Duty F-250, F-350 and F-450. Original broad F-250/F-350 coverage remains, with ten named groups supported by the exact selected-part retailer table: King Ranch, Lariat, XL and XLT 2011-2016 plus Platinum 2013-2016 on each F-250 Super Duty and F-350 Super Duty. The manual also supports F-450 Super Duty 2011-2016 at model level without inventing Base or individual trims. All applications require actual 6.7L diesel and the illustrated sensor, inlet gasket, mounting and coolant-hose arrangement. Individual F-450 trim/year proof beyond limited indexed retailer rows remains unresolved; no range is inferred from the first page of a paginated table. Broader F-550 retailer positives require exact housing/configuration confirmation. No gasoline or later-generation truck is covered. The D-550-24 reference is conditional on its actual exempt applications, not a blanket exemption for every mechanical-fitment year.

One selected dry filter is supplied; the shared bill’s blue oiled 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 dry bench flow is 695 versus stock 480 CFM at 7 inches H2O. Marked dyno differences are 16.35 HP and 31.19 lb-ft; maxima differ by 16.00 HP and 7.31 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 51-11872-1. 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.
The exact current primary specifies XLPE polymer housing and tube, rather than a generic metal top-half shield. Only one selected three-layer dry filter is supplied; other media shown in the complete shared bill are alternatives. Actual bench flow at 7 inches H2O is dry 695, oiled 750, gold seven-layer 690 and stock 480 CFM. The selected dry increase is approximately 44.79%, corresponding to the rounded 45% headline; oiled 750-CFM results are separate. Its actual linked dyno marks 316.76 versus 300.41 HP and 605.10 versus 573.91 lb-ft at 2750 rpm, differences of 16.35 HP and 31.19 lb-ft. Run maxima instead differ by 16.00 HP and 7.31 lb-ft. The chart states SAE smoothing 5 but omits complete vehicle, dates, medium and matched environmental conditions. No guaranteed gain or 31-lb-ft peak-to-peak difference is claimed. The exact manual requires both negative battery terminals disconnected and both reconnected, retains original inlet and mounting seals, and has specific 2015-2016 coolant-tube tie replacement. D-550-24 full exact scope remains unresolved after an earlier access challenge; the primary says some or all applications are exempt. Verify the exact order and exclusions rather than extending exemption to all listed years. Exact retailer named coverage and manual model-level F-450 coverage do not establish every F-450/F-550 trim or chassis configuration.
