08 Buick Regal and 10 Buick Regal are both 2.4 displacement throttles. Can they be used universally?

The throttle of these two cars is not universal.

The main reason is that the engines and control systems of these two models are different, and different engines and control systems need different throttles to match and optimize. Even if it is a car of the same brand and model, the models of different years may be upgraded or improved because of the engine and control system, resulting in the accessories such as throttle no longer being common.
