aFe 56-70039D is the Takeda Momentum intake for specified Subaru Outback 2015–2019 H4-2.5L applications without the factory HID lighting package. One Pro DRY S filter fits the window housing and two-piece XLPE tube assembly. The original MAF, crankcase-vent hose, mounting bushings and scoop transfer.
The exact manufacturer shared manual lists Subaru Outback 2015–2019 H4-2.5L and explicitly names both selected media versions. The current R manufacturer page excludes vehicles with the factory HID lighting package; exact D retailer information repeats that exclusion. The original four named rows remain: 2.5i/2.5i Limited/2.5i Premium 2015–2019 and 2.5i Touring 2017–2019, conditional on actual lighting and intake equipment. A trim name alone does not prove absence of HID; verify the installed factory lighting package before ordering. These bounds are retained without treating retailer named-trim coverage as an override of the HID restriction. No H6, turbo, Legacy or later-generation fitment is inferred. A current standalone D manufacturer product page was not located; its shared-manual facts and exact retailer qualifications remain explicit.

The shared BOM prints R24/R21 filter prefixes; an exact D retailer identifies 21-90101 as the service filter, while a current standalone manufacturer D page remains unavailable. Preserve that printed-versus-service distinction when matching a replacement. The filter-flange clamp is shown without a separate BOM code/count and is distinct from the four supplied coupler clamps. Transfer the two original mounting bushings and steel inserts, retain the two housing screws and seat the separate locating stud in its bushing. Restore the original tube-mount panel clip and the scoop’s two panel clips. No new vent hose, elbow, MAF sensor, extension harness, isolation mount or trim seal is listed. The plug is in the BOM without a dedicated illustrated installation step; no plug-dependent performance assumption is added.
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 selected Pro DRY S filter; the alternate-media row is not a second supplied filter.
Does the dry version need oil?No. D uses three-layer oil-free synthetic media; R uses five-layer pre-oiled cotton gauze.
Does this fit a factory HID-equipped Outback?No. The manufacturer excludes the factory HID lighting package; verify actual equipment even when a named trim appears in the table.
Is the intake tube one piece?No. It has separate B1 and B2 XLPE sections, connected with the supplied bellows and hump couplers.
Which original mounting parts transfer?Two rubber bushings and steel inserts, two housing screws, the tube-mount panel clip and both scoop panel clips remain in use.
Is a new vent hose or MAF supplied?No. Transfer the original crankcase-vent hose and MAF; the kit supplies two M4 screws without a stated length.
Can the R dyno be applied to the dry version?No. The family bench chart explicitly separates media flow, but the observed vehicle dyno is an R-media test.
What torque and inspection interval apply?No numeric torque is supplied. Check screws, clamps and connectors after 100–200 miles.
Verify aFe 56-70039D. Work on a cool engine. Remove the two scoop panel clips and retain the scoop. Remove and retain the intake-tube mount panel clip. Squeeze the original spring clamp and disconnect the crankcase-vent hose, disconnect the MAF harness, loosen the throttle-body and airbox clamps and remove the original tube. Remove and retain the two housing screws, then lift out the original airbox. Push out the steel inserts and remove its two rubber mounting bushings; transfer both inserts and bushings to the new housing. Seat the new housing, ensuring the locating stud enters its mounting bushing, and secure it using the two original screws. Install the selected filter with its clamp. Assemble the bellows and hump couplers on the B2 chamber tube with one #044 clamp each, then place the other two #044 clamps on their exposed ends. Fit B2 to the throttle body without fully tightening. Transfer the original MAF onto B1 using the two supplied M4 screws and T20. Insert B1 into the bellows first and then into the filter, keeping clamps loose for alignment. Reconnect the original vent hose, restore the tube-mount panel clip and MAF harness, then restore the original scoop and both panel clips. Align and tighten all filter and coupler clamps. Check all screws, clamps and connectors after 100–200 miles. No numeric torque, battery-disconnection or engine-cover procedure is specified.
The actual manufacturer-linked family flow chart explicitly identifies Pro 5R at 255 CFM, Pro DRY S at 220 CFM and stock at 170 CFM, measured at 7 inches H2O. The dry comparison is approximately 29.4%, rounded to 30% by exact retailers. Retailers advertise 3 hp/3 lb-ft; a separate exact D dyno image was not located, so the R test is not certified as a dry-media gain. Results depend on test configuration and are not guaranteed for every vehicle. The shared exact manufacturer manual states this product is not CARB exempt and unavailable for purchase in California or use on California-registered vehicles.
