I want to learn everything I can about ITB's. Yesterday I learned that the OEM throttle body is used to operate the 4 ITB's through a mechanical linkage. I understand they did this probably to simplify the drive-by-wire environment.

My question: Is the OEM throttle body actuator robust enough to handle the increased load of 4 spring-biased valves and the linkage attached to them?
