aFe 51-73115 is the Momentum GT Pro DRY S intake for qualified 2017-2020 F-150/Raptor 3.5L twin-turbo applications. One 21-91092 filter with three oil-free synthetic layers connects to a molded branched tube and housing with inspection window. The original temperature sensor and wastegate-control component transfer, and a directional insert fits the original driver-side turbo-inlet vent connection.
Current manufacturer page and exact twenty-page manual name F-150 and F-150 Raptor 2017-2020 with 3.5L twin-turbo EcoBoost. Existing model-only F-150 row and bounds remain conditional on that actual engine and the illustrated original inlet/vent/sensor configuration; a supported named Raptor row is added within the same years. No V8, later PowerBoost or Raptor R application is inferred. Other engines and named trims require their own exact selected-part evidence.

Other filter media in the shared bill are alternatives, not bundled elements. Original temperature sensor, housing mounting grommet and screw, wastegate-control component and wiring are retained. No new MAF, replacement wastegate controller or extension harness is itemized. The molded branched tube differs from the two-aluminum-tube XP kit; do not substitute that kit coupling or breather bill.
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 choices are separate versions.
Which vehicles and engine are documented?The exact current dry page and manual name F-150 and F-150 Raptor 2017-2020 with 3.5L twin-turbo EcoBoost. Match the actual sensor, inlet and vent arrangement.
Is a MAF sensor included?No. The original air-temperature sensor transfers into the supplied IAT fitting and grommet.
Which way does the vent insert face?Its slash cut faces the turbo inlet. It must seat fully and must not rotate.
Must the valve-cover end of the vent line be removed?No. Release the original inlet end while protecting and retaining the vent sensor and harness.
Is drilling mandatory?No. Two quarter-inch housing holes are optional for harness clips; choosing that route also requires relocating and retaping the original clips.
Do the dyno gains isolate the intake change?No. Baseline and intake runs differ in exhaust, intercooler, load and correction factor, in addition to the intake.
What torque and follow-up apply?No numeric torque is stated. Check bolts, clamps and connectors after exactly 200 miles; battery disconnection is only an optional code-clearing method.
Verify aFe 51-73115. Read all twenty pages and figures A-M on a cool engine. Disconnect the original temperature harness, unclip coolant line and remove original intake tubes, filter and upper housing. Release rear wire and wastegate-control component, remove original housing screw and two rivets, and lift out housing. With original turbo inlet tubes still on the engine, access the driver-side valve-cover vent connection. Release its inlet-side clip without disconnecting the valve-cover end or damaging its sensor and harness. Fully seat vent insert with slash cut facing turbo inlet; it must not rotate. Reconnect and tug-check the fitting. The manual offers code-reader clearing or battery disconnection if codes require clearing; battery removal is not a general mandatory step. Transfer original housing grommet and fit edge trim. Optional harness retention requires two marked quarter-inch housing holes and repositioned, retaped original push clips. Seat housing on original mounts, restore original screw, install both supplied rivets and reconnect wastegate-control component to its housing bracket. Push in selected filter until locked. Fit supplied grommet and aluminum temperature fitting into new tube. Fit both couplings and clamps loosely and transfer original temperature sensor. Slide couplings over original tubes first, then insert new tube into filter. Align, tighten all clamps and reconnect temperature harness. Complete optional clip routing if chosen, verify secure components and remove window film. No numeric torque is specified. Check bolts, clamps and connectors after exactly 200 miles.
The actual linked family flow chart identifies Pro DRY S 595 versus original 450 CFM at 7 inches H2O, approximately 32.2 percent. The oiled 645-CFM row is a separate media choice. The linked dyno identifies Momentum GT without naming filter media and is shared with the oiled page, so it is not independent dry certification. It marks 22.04 hp and 25.77 lb-ft differences at 4500 rpm; run maxima differ by 12.79 hp and 8.72 lb-ft. Baseline June 6, 2017 uses SAE 1.03, original intake and downpipes, aFe V3 cat-back exhaust, original wheels, fifth gear, 20-percent load, sport mode and traction control off. Intake June 7 uses SAE 1.02, original exhaust, aftermarket intercooler, fifth gear and 30-percent preload. These equipment, load and correction differences prevent an isolated intake-only gain claim. All twenty manual pages were read and its full bill viewed; bytes match the previously fully illustrated exact family manual, figures A-M. Optional housing harness retention requires two marked quarter-inch holes and relocated, retaped original clips, despite generic no-drilling copy. No mandatory battery-disconnection step or numeric torque is specified. Current manufacturer and exact manual state not CARB exempt and unavailable for purchase in California or use on California-registered vehicles. Exact dry selected-part retailers corroborate the named Raptor addition within the original model-only years.
