Subaru owners seeking more than 600 horsepower may be limited by their OEM throttle body, which is not large enough to handle larger turbochargers. To address this issue, inferior aftermarket alternatives have been used, causing problems such as sticking, poor idle quality, and difficult installation. Fortunately, IAG has developed adapter plates that allow owners to upgrade their OEM throttle bodies to a larger, high-quality unit with a 76mm bore, offering nearly 25% more flow than stock. Say goodbye to compromising drivability for horsepower - with IAG's Big Bore throttle body, owners can have both.
NOW EVEN EASIER TO INSTALL
The installation process is now simpler compared to other options offered. Just replace the OEM Subaru throttle body with the included adapter and new 76mm throttle body onto the intake manifold. There is no need for complex disassembly or dealing with springs, and the OEM connector can be easily plugged in. (Relocating the MAP sensor may be necessary)
CNC MACHINED ADAPTER PLATES
Crafted from durable 6061 aluminum, these plates sport an O-ring sealing surface. With this kit, you'll receive a Big Bore 76mm Throttle Body and IAG adapter plate, along with all required hardware for a seamless installation. Adapter plate comes in anodized black finish.
