Though they dont have a huge selection, for what I needed, audipartssuperstore.com was right on. I am going to pick up a 01 225qr on saturday, and wanted to bring a greentop coolant sensor, theirs comes bundled with the retainer clip and o-ring for ~22, overnight shipping was half the cost of ecstuning, and they had really prompt email feedback and tracking info. If you happen to need something they have, might wanna check it out.

 

Yea i never understood why it was "Super" , but good for you though.
