aFe 54-22979 This 12-inch intake-air-temperature harness extension allows the original IAT sensor connection to reach a relocated sensor position on qualified Ford F-150 2.7L or 3.5L twin-turbo EcoBoost applications. One loomed extension with factory-style two-pin connectors is supplied. It does not include a filter, airbox, coupling, intake tube or replacement sensor.
Current exact primary headline identifies F-150 2015-2026, V6 2.7L or 3.5L twin-turbo EcoBoost, while its detailed description and own eight-page manual identify 2015-2021. The existing model-level 2018-2020 row is broadened to current manufacturer 2015-2026 scope without losing original coverage, with later-year connector/configuration qualification. Exact selected-part retailer tables support eleven genuine named groups through 2025 as shown below; 2026 named-trim proof remains held. Listed trims do not imply both engines were offered in every trim/year: use the actual qualifying engine, matching two-pin IAT connectors and relocated-sensor requirement. No V8, diesel, unrelated sensor, Expedition or Navigator scope is inferred from nearby intake products.

| 1 | 05-70023 | IAT harness extension |
The exact bill lists only one extension harness. No replacement IAT sensor, MAF sensor, filter, coupling, airbox, mounting hardware or intake assembly is itemized. Generic Filter Included/Coupler Included flags do not establish those parts. Use the actual two-pin connector interface; this harness does not change the intake physical fit or substitute for another sensor harness.
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 05-70023 IAT harness extension. No replacement sensor, filter, coupling or complete intake is itemized.
What length and connectors does it use?The manufacturer specifies 12 inches and factory-style two-pin connectors.
Is it a MAF harness extension?No. It extends the original intake-air-temperature sensor connection; verify actual connector and sensor identity.
Which end connects where?The exact manual says female extension end to original vehicle harness and male extension end to original IAT sensor.
Does it require cutting or splicing?No. The manufacturer describes plug-and-play installation without wire modification.
Are all later named trims verified through 2026?The current primary model headline ends in 2026; reviewed exact named-trim tables end in 2025 and the own manual in 2021. Later configurations remain qualified.
Does the extension itself establish a power gain or street exemption?No standalone gain test is linked, and current no-EO wording conflicts with the own manual race-only restriction. Parent intake requirements remain separate.
What torque and follow-up are specified?The own manual gives no numeric torque, battery step or mileage interval. Verify connector engagement and safe slack/routing.
Verify aFe 54-22979. Read all eight pages and figure A. Work on a cool engine and identify the original intake-air-temperature connector for the actual qualifying vehicle/engine. Disconnect original harness from the IAT sensor. Connect the female end of the supplied extension to the original harness, then connect the male end to the original sensor, as stated in the exact manual. Verify both connectors fully engage and the added harness reaches the relocated sensor without tension or contact with hot or moving parts. This is an electrical extension; no filter, tube, heat shield or coupling installation is prescribed by its own procedure. The manual specifies no battery-disconnection step, numeric torque or mileage recheck interval.
Manufacturer states the extension allows relocation up to 12 inches and uses tested factory-style two-pin connections. No current linked standalone test establishes horsepower, fuel-economy or heat-soak gains; secondary retailer claims are not adopted as measured benefits. Current headline extends to 2026 beyond 2021 detailed/manual scope, and exact named retailer tables end in 2025; connector and sensor configuration remain essential. Current primary says this accessory does not require a CARB EO, but the own manual retains a California race-only restriction and older exact retailers also show California-restricted flags. This source conflict remains qualified without declaring blanket street legality or changing historical metadata. A direct retailer open returned HTTP 403 and was stopped; the existing normal indexed exact table was used read-only. Turn14 authenticated access is unavailable; prices remain unchanged.
