Im upping the A6 (non Z51) with a oem Z06 diff, although quite a few said I dont need a cooler I think I want one (DD, no track events, at this time). The diff is new with fittings for a cooler but its without the lines or the cooler.
I know the diff itself is a direct bolt up to a base A6 but is the cooling system as well?
I cant seem to find an aftrmkt one under $800-$1300 nor can I find the oem parts (I did find the little Z06 oem side mount cooler for 150).
I did find an inexpensive universal B&M SuperCooler or Hi Tek but its without a pump nor does it mention a pump, dont I need a pump?
I have been running mine for over 2 years without a cooler, I just routed the lines in a loop to keep the fluid flowing. I dont think you need one for a DD.
