Wiper arms tend to refer to the metal arms attached to the wiper motor. One never replaces these on a normal car.
Wiper blades tend to refer to the object that attaches to the arms and actually contacts the windshield.
Wiper refills tend to refer to rubber refills for wiper blades that support refilling with new rubber. I'm not aware of any aero style blades (such as used on the B8 and B9) supporting refills.
So presuming the OP is asking for new wiper blades, as his have worn out. As noted, the Audi B8 and B9 arms use a 16mm top lock mount; make sure the blades you get have the adapter to mount to them.
Bosch might be the OE for the blades the Audi factory uses, but there's no reason to presume any Bosch aftermarket (OEM field replacement) product is the same caliber as what they are supplying Audi. You want Audi original, you buy Audi OE, not Bosch OEM.
I've been happy with the Michelin ones I've been using most recently. But they, like every aero style I've tried since getting this car 10 years ago, have short lives compared to the style on my original G35. 6 months and they are all pretty done.
