In the hunt for more than 600 horsepower Subaru owners can be limited by their OEM throttle body. The OEM units just aren't big enough to meet the demands of larger upgraded turbochargers. For years those who were seeking to upgrade this component were forced to use inferior aftermarket alternatives. These aftermarket throttle bodies were prone to issues like sticking, poor idle quality, and difficult installation. IAG is pleased to announce that these owners are no longer forced to compromise drivability for horsepower. With the introduction of our new adapter plates owners are able to upgrade their OEM throttle bodies with a larger quality unit. The Bosch throttle body offers a 82mm bore which is over 36% larger over stock. Intended for race applications, this unit requires the use of Stand-alone Engine Management (Motec, Haltech etc). The package includes a wire harness adapter to make the installation much easier than other options previously available. Custom calibration using your stand-alone engine management is required. The plate is machined from 6061 aluminum, and features an O-ring sealing surface. Each package includes a brand new Bosch 82mm Throttle Body, IAG adapter plate, and all the necessary hardware to complete the installation.
