IAG Big Bore 76mm Throttle Body Adapter for Process West Intake Manifold; Black Finish.

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 that is sold separately.The Big Bore throttle body offers a 76mm bore which is nearly 25% larger over stock. Best of all, the installation is much easier than other options previously available. Simply drill out the rivets holding the motor to your OEM throttle body, remove the motor assembly, and install it to the Big Bore throttle body u
