I know AAV is the auxilliary air valve that lets air bypass the throttle body to raise the idle during cold starts, and the WUR is the warm up regulator... but what is an AAR?

Only advantage to removing the AAV is loosing a tiny bit of weight... it won't make anything run better when warmed up, and the idle will be painfully low during a cold start without it.

The WUR is a major part of CIS so you can't remove that.

Is the AAR just another casual name for the AAV?
