This will ensure that the turbo is supplied with the coolest air possible and will provide a little less thermal load on the motor and its supporting systems. Additionally, running a custom hard pipe instead of the flexible...

Although a gain in horsepower is usually not evident when swapping a larger throttle body onto a pressurized (turbo charged) intake manifold, increasing the size of the throttle body will improve the motor’s on/off throttle response as well as boost response.
