aFe 54-13025D is the Pro DRY S Rapid Induction intake for qualified Ford/Lincoln 3.5L twin-turbo EcoBoost applications. The current manufacturer uses Rapid Induction branding, while the shared manual and older catalog call it Stage-2. One three-layer oil-free synthetic filter, a snap-on upper heat-shield/housing assembly and a molded tube retain the factory lower airbox and its mounting clips. Transfer the original intake-temperature sensor; no new sensor is supplied.
Both current exact pages identify Taurus SHO and Flex 2010-2019 and Explorer 2013-2019 with the 3.5L twin-turbo EcoBoost. The shared manual has older Taurus end year 2018 and earlier Explorer Sport 2012/MKS 2009 starts; those earlier starts are not added. Preserve original Explorer Platinum 2016-2019, Sport 2013-2019, Taurus SHO 2010-2019 and MKS 2010-2016 bounds. Exact selected-part retailer tables restore Flex Limited 2010-2019, SEL 2010-2011 and Titanium 2011-2012. Every row requires the actual twin-turbo engine and corresponding housing/sensor arrangement. The broad existing MKS row remains engine-qualified rather than treating EcoBoost as a new trim. Retailer naturally aspirated Taurus SE/SEL/Limited and MKT claims lack reconciled exact engine/housing evidence and are not added.

The alternative filter entry in the shared bill is not a second filter supplied. Original lower airbox, clips and temperature sensor remain in use. No new MAF sensor, temperature sensor, separate sensor screws or complete replacement lower airbox is itemized. The manual bills the cover and fitting but its short numbered procedure does not describe every separate fitting/cover attachment; follow the complete illustrated assembly and verify actual parts.
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 21-90095 with three-layer oil-free synthetic media. Its alternative media entry in the shared manual is not an additional filter.
Does Rapid Induction replace the entire factory airbox?It replaces the upper assembly and retains the factory lower airbox and clips. The bill supplies an upper housing/heat shield and cover.
Is the sensor a new MAF sensor?No new sensor is itemized. The illustrated procedure transfers the original intake-temperature sensor and reconnects its original harness.
How is the original temperature sensor removed?Disconnect its harness and turn the sensor one-quarter turn counter-clockwise, taking care not to damage it. Transfer it into the supplied grommet arrangement.
Why must the filter part number be checked?The current narrative says 3.5-inch flange while the exact service listing says four inches. The seven-inch selected filter part number is established; the conflicting flange dimension is qualified.
Why might the battery need to move?The manual permits loosening two battery hold-down nuts and sliding the battery rearward for installation clearance if needed. Restore secure retention; no battery relocation kit is supplied.
Do all named vehicle rows cover every 3.5L engine?No. The application is the twin-turbo EcoBoost arrangement. Existing MKS coverage is engine-qualified, and new Flex named rows require that same actual engine and housing.
What performance, torque and recheck limits apply?Shared chart gives 555 CFM for this media versus 395 stock. Shared dyno power maxima differ by +7.07 hp while torque maxima differ by -1.63 lb-ft; advertised +2 lb-ft is not that peak calculation. No numeric installation torque is given. Check connections after 100-200 miles and retain manufacturer California restrictions.
Verify aFe 54-13025D. Read the complete manual, work on a cool engine and disconnect the negative battery terminal. Disconnect the intake-temperature harness and remove its plastic tie from the airbox-lid corner. Loosen the rear rubber-tube clamp, release both latches and remove the upper cover, tube and original filter while retaining the lower box. Turn the original temperature sensor one-quarter turn counter-clockwise to remove it without damage. Fit the supplied grommet to the new tube and transfer the sensor as illustrated. Install the selected filter in the upper housing and clip the assembly to the original lower airbox. If extra clearance is needed, the manual permits loosening the two battery hold-down nuts and sliding the battery rearward; restore secure battery retention after positioning. Fit the bellows to the inlet connection with supplied clamps initially loose, install and align the new tube, tighten clamps and reconnect the temperature harness. Verify secure assembly and check bolts, clamps and connectors after 100-200 miles. No numeric torque is specified.
Both exact current pages, their own twelve-page manuals, all three shared contact sheets, bill and Figures A-F were reviewed in full. Manuals have identical SHA-256 hashes and full text. All four linked flow/dyno images were visually inspected; the two flow files are identical and both dyno files are identical. Shared flow chart labels Pro 5R 570, Pro DRY S 555 and stock 395 CFM at 7 inches H2O, about 44.30% and 40.51% respectively. The shared dyno chart reports 299.52/292.45 hp and 332.55/334.18 lb-ft maxima; +7.07 hp and -1.63 lb-ft are differences between separate maxima at different speeds. The advertised +2 lb-ft point is not marked. Chart shows Stage-2 and SHO baseline, SAE 1.02 and smoothing 5 with different temperature/pressure/humidity, but no selected filter media, actual model year, dates, gear or exhaust configuration; it is not independent dry-media testing. No output, fuel-economy or delivered-price guarantee is made. Turn14 exact-product information remains unavailable without authenticated access. Original coverage and protected commercial data are preserved; price is unchanged.
