There is a thread a few lines away from this that gives part numbers for the throttle bodies.
I have had the throttle body off my car twice, once for cleaning the throttle body and once to replace the INRC control box. (I usually don't remove the throttle body for cleaning, I believe it is not necessary) I reused the original gasket both times. The gasket stayed behind on the intake manifold. If you need to clean the EGR passages, the gasket will need to be removed from the manifold and it is more likely that it will need to be replaced.
