Throttle Body

The throttle housing is die-cast in aluminum. The throttle disc is also made of aluminum. Under the plastic cover there are position sensors that read off the position of the throttle disc as well as two motor connections to the motor that turns the throttle disc, depending on the driver's requested throttle disc angle.

The throttle body (TB) does not need to be cooled, but may need to be heated. An O-ring in the intake manifold ensures the seal between the intake manifold and throttle body (TB).
