aFe 54-73203 Momentum GT system combines one Pro 5R oiled filter, molded intake tube and one-piece housing with inspection window for the 2015-2017 Mustang GT 5.0L. Three billet-aluminum fittings restore the original line connections; the original one-inch hose and spring clamp also reconnect.
Current exact manufacturer page and sixteen-page manual identify Mustang GT 2015-2017 with the 5.0L V8. Existing GT and GT Premium 2015-2017 and GT 50 Years Limited Edition 2015 rows and their original tags remain unchanged. This does not establish EcoBoost, V6, GT350 5.2L or 2018-up application. Confirm original sensor and all line connections before ordering.

The dry filter row in the shared bill is an alternative version, not a second supplied filter. Keep the provided filter-flange clamp in place as illustrated in addition to the itemized housing T-bolt and two coupling clamps. Reuse original MAF, housing grommet and metal sleeve, guide bushing, fender bolt, line connectors and one-inch hose spring clamp. The manual does not supply replacement hoses or an engine cover.
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 24-91062 Pro 5R oiled filter with five cotton-gauze layers; the dry alternative is not bundled.
Which years and engine are identified?Current manufacturer and exact manual identify Mustang GT 2015-2017 with 5.0L V8. Existing three named application rows remain unchanged.
How many aluminum fittings are included?Two small and one large NPT fittings are itemized. They do not bottom out and must not be overtightened.
Which MAF screws are supplied?Two M4 x 0.7 x 10 mm Torx screws secure the transferred original sensor.
How does the housing mount?Transfer the original grommet, metal sleeve and rubber guide bushing, align the snorkel over the original duct and restore the original fender bolt.
Does the MAF harness need repositioning?The manual relocates the terminated fender connector, releases a lower push clip for slack and routes the MAF harness over the snorkel.
Does the dyno prove 24 lb-ft peak gain?The marked separate-rpm torque difference is 23.10 lb-ft and run-maxima difference is 12.93 lb-ft; advertised 24 lb-ft is qualified rather than called a peak-to-peak result.
What torque and follow-up apply?No numeric torque or battery-disconnection step is stated. Check bolts, clamps and connectors after exactly 200 miles.
Verify aFe 54-73203. Read all sixteen pages and figures A-J. Work on a cool engine. Remove engine cover, loosen original tube clamps, disconnect three fittings and slide back the spring clamp to disconnect the one-inch hose. Remove the tube. Retain the fender housing bolt, disconnect MAF and release its harness clips. Pull the sound chamber upward from the air box and remove the original housing. Relocate the terminated connector on the fender well to the forward hole illustrated and release the lower harness push clip for MAF wiring slack. Transfer mounting grommet, metal sleeve and rubber guide bushing. Transfer MAF with the supplied M4 x 10 mm Torx screws. Install all three aluminum fittings in their correct tube positions; NPT threads do not bottom out and must not be overtightened. Place coupling and clamps on the small tube end, initially loose. Seat housing with its snorkel over the original air duct and guide bushing flat on the fender; route MAF harness over the snorkel and restore the original fender bolt. Fit the large housing clamp loosely and insert selected filter with its provided flange clamp in place. Insert tube into filter first, reconnect all fittings and hoses, then slide coupling over throttle body. Check hoses cannot pull off; the bottom-fitting hose may require rerouting. Tighten clamps, reconnect MAF, restore one-inch spring clamp and engine cover. Check all bolts, clamps and connectors after exactly 200 miles. The manual states no battery-disconnection step or numeric torque.
The actual manufacturer-linked bench chart identifies selected oiled intake at 221 versus original 177 CFM at 1.5 inches H2O, approximately 24.9 percent, rounded to 25 percent. The 2015 Mustang dyno marks 223.77 versus 208.42 hp and 345.03 versus 321.93 lb-ft at different rpm points, differences of 15.35 hp and 23.10 lb-ft. Advertised 24 lb-ft is not that exact marked difference. Run maxima are 404.77 versus 382.17 hp and 360.72 versus 347.79 lb-ft: differences of 22.60 hp and 12.93 lb-ft. Baseline April 13, 2015 uses SAE 1.03; intake November 20, 2015 uses SAE 1.01 with different weather. Both note original manifolds and exhaust, fourth gear and 10 percent before run; intake also lists no tuner, HRE wheels/Toyo tires and blower fan. These conditions limit generalization. Current primary and exact manual identify 2015-2017, correcting the older 2015-only title. Current manufacturer states this product is not CARB exempt and is unavailable for purchase in California or use on California-registered vehicles. Turn14 authenticated access is unavailable; prices remain unchanged.

Compare what the package supplies before choosing between the two routes.For a naturally aspirated, turbocharged or supercharged engine, the connection and sensor arrangement are part of the design.

An open-element or short-ram layout places the filter differently and can change the audible induction character. A longer routed intake, a short-ram system and a factory-airbox tube replacement involve different installation scopes.Compare the actual filter position, heat-shield/enclosure design, retained ducts and access for maintenance. A cold-air label alone does not establish a lower inlet temperature in every driving condition or a fixed horsepower gain.
