ive been down this road many times and ive used non mopar builders 90% of the time because like you said its an air pump what logo on it shouldnt make a difference right? but it does.....i know the pride thing and as long as the motor doesnt blow up most are content with the results as where a mopar person will go the extra mile in my experience.now there are some good shops around but they have bigger fish to fry i prefer somebody that can give me the time.
