aFe 51-73116 is the Momentum GT Pro DRY S intake for qualified 2017-2019 F-250/F-350 Super Duty 6.2L gasoline applications with the original mechanical fan. One 21-91061 element uses three oil-free synthetic layers and a 9-inch height. The molded housing and tube retain original mounts, while the passenger-side vent connection uses the supplied hose only when that original hose is equipped.
Current exact manufacturer page and sixteen-page manual identify 2017-2019 F-250/F-350 Super Duty 6.2L V8 gasoline with original mechanical-fan configuration. Exact dry retailer tables support King Ranch, Lariat, Platinum, XL and XLT for each Super Duty model in those years. These ten named groups are restored while original two F-250/F-350 model-only rows and bounds remain. Positive retailer Limited and XL Plus labels require exact engine/market reconciliation before new mapping. Later 2021 retailer headline wording conflicts with current 2017-2019 primary/manual scope and is not added. No 6.7L diesel, 6.8L or 7.3L gas application is inferred.

The oiled-filter bill row is a separate configuration. The hose is described as fuel hose in the bill but the actual procedure uses it at the passenger-side vent connection and white plastic tee, not in fuel plumbing. If that original hose is absent, use the 1/8-inch NPT plug and omit the passenger-side hose/mini-clamp connection. The procedure calls for provided threadlocker at the fittings; it is not separately quantified in the bill. No new MAF or MAF screws are itemized. Reuse the two original housing screws, housing grommets and original tube-support mounts. The optional scoop is not included.
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 21-91061 Pro DRY S element with three oil-free synthetic layers and 9-inch height. The oiled row identifies a separate choice.
Does this apply to the diesel Super Duty?Current manufacturer and manual identify 2017-2019 6.2L gasoline with original mechanical fan; no diesel application is established.
What if the passenger-side hose is absent?Use the supplied 1/8-inch NPT plug to close that tube port and omit the conditional hose connection.
Where does the supplied 9-inch hose connect?On an equipped vehicle it joins the passenger-side brass fitting to the original white plastic tee, secured by the two mini clamps.
Does the optional scoop come in the box?No. It is sold separately and uses its own installation instructions. The intake includes an auxiliary-opening plug.
Are new MAF screws included?No MAF or MAF screws are itemized in this exact bill or sensor-transfer procedure.
Are the linked tests independent dry-media certification?Both charts identify the separate 54-73116 oiled version. The page dry airflow and gain claims remain qualified; different test pressure and media cannot be interchanged.
What torque and recheck apply?The manual gives no numeric torque or battery-disconnection step. Check clamps and connectors after 100-200 miles.
Verify aFe 51-73116. Read all sixteen pages and figures A-I on a cool engine. Remove and retain the two housing screws and loosen the original tube clamps. Lift out the original housing. Disconnect the original vent hoses, releasing an equipped passenger-side hose at its white plastic tee. Some vehicles lack that hose. Pull the original tube upward and away from throttle body, keeping its mounting grommets in place. Transfer original airbox grommets to new housing. Insert selected filter, install its clamps and tighten only the larger housing T-bolt initially. Seat housing in the original mount. Fit bellows and clamps loosely to the small tube end. Install the two brass nipples and aluminum fitting with the threadlocker directed by the manual. If there is no original passenger-side hose, close that tube port with supplied 1/8-inch NPT plug. Slide coupling over throttle body first, then connect the other tube end to the filter and tighten clamps. Restore original vent connections; for an equipped passenger-side hose, connect the supplied 9-inch hose between the tube brass fitting and original white tee, securing both ends with mini clamps. Restore the original two housing screws. An optional separately purchased scoop follows its own sheet; without it, choose the housing opening plugged or open as directed, recognizing engine-compartment air and sound tradeoffs. Verify every connection. Check clamps and connectors after 100-200 miles. No battery-disconnection step or numeric torque is stated.
The exact dry manufacturer page advertises 550 CFM at 7 inches H2O, 18 percent more airflow and 15 hp / 17 lb-ft. Both actual linked charts identify the separate 54-73116 oiled intake, so they do not independently certify dry performance. The oiled flow chart shows 269 versus original 228 CFM at 1.5 inches H2O, a different pressure from the page 550-CFM figure. Its dyno marks 15.15 hp and 16.56 lb-ft differences at 4799 rpm; run maxima differ by 8.94 hp and 10.75 lb-ft. Intake June 21, 2017 uses SAE 1.04 and baseline June 12 uses SAE 1.01. Both list cat-back exhaust, 40-inch tires, third gear and 20-percent preload. Those conditions further limit generalization. The exact sixteen-page manual explicitly identifies this dry choice; all pages were read and its full bill viewed. Its bytes match the previously fully illustrated family manual, figures A-I. The fuel-named hose in the bill is used for ventilation, and vehicles without that passenger-side hose require the supplied closure plug instead. No new MAF or MAF screws are itemized. Exact dry named tables support the ten restored groups; positive Limited and XL Plus retailer labels require exact engine/market reconciliation, and a later-year retailer headline does not establish extension beyond the current 2017-2019 primary/manual range. Current manufacturer and manual state not CARB exempt and unavailable for purchase in California or use on California-registered vehicles.
