Description

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 OEM quality unit. The Big Bore throttle body offers a 76mm bore which nearly 25% larger over stock. Best of all, the installation is much easier than other options previously available. Simply remove the OEM Subaru throttle body, install the supplied adapter and new 76mm Throttle body to the intake manifold. No complicated disassembly, no springs, and the OEM connector is plug and play. The plates are machined from 6061 aluminum, and feature an O-ring sealing surface. Each package includes a brand new Big Bore 76mm Throttle Body, IAG adapter plate, and all the necessary hardware to complete the installation. The adapter plates are available in anodized black finish.
