Speed Density MAF Adapter Harness 2015-2021 Subaru STI

By allowing you to easily plug in any standard AEM or GM Intake Air Temp (IAT) sensor, this harness from iWire makes it simple to convert your MAF-equipped Subaru car to Speed Density tuning. The iWire harness is built to last, with Milspec grade materials like flame retardant, corrosion, and abrasion resistant Tefzel wire. The harness is also wrapped in Raychem DR-25 heat shrink tube that can withstand the harsh environment of the engine bay. The IAT sensor plug is booted and the MAF sensor connector is potted to ensure a true weatherproof seal and secure wire connections. Standard length from MAF to IAT is 36 inches.
