Don't cut out the stock Mass Air Flow (MAF) plug to convert to Speed Density (SD) in your 2002-2007 Subaru. Use iWire's plug and play Speed Density harness that converts the stock connector to the new Intake Air Temperature Sensor connector. Our harness is built to last with Mil-spec grade materials like flame retardant, corrosion, and abrasion resistant Tefzel wire. We've also wrapped it in Raychem DR-25 heat shrink tube that can withstand the harsh environment of the engine bay. The Inlet/Intake Air Temperature or 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.
Our standard adapter length is 36 inches which works with most common applications. We can also do a 48 inch version which works for applications with a Front Mount Intercooler or any setup that the IAT sensor is not on or near the manifold and/or throttle body.
Select "Standard Connector" for most IAT sensors including standard GM, IAG IAT sensor as well as AEM part number 30-2010.
Select "Alternate Deutsch Connector" for the 1/8" NPT Thread Air Temperature Sensor found on AEM part number 30-2014.
Optional 02-07 MAP Adapter can be found here for those who use an AEM Manifold Absolute Pressure (MAP) sensor adapter for upgrading when the stock MAP reaches its limit. Built to the same specifications as the MAF harness for a high quality connection that will resist the high temperature engine bay location on the intake manifold.
