This adapter breaks out the IAT signal from the MAF sensor on Subaru WRX 2008+ EJ255, and 2015+ STi EJ257 engines to relocate to intercooler piping for more accurate plenum temperature, as opposed to ambient intake temperature. Made with hi-temp nylon braided sleeving, genuine OEM connector plugs, seals, cavity plugs & terminals, manufactured and assembled at our facility in the US. (pictured w/ EV1 connector – other options available!)
