S5 TII Which Radiator
 

Purchased new and yesterday the factory rad let go and car was taken home on a flatbed, so after doing some research, still would like to know any suggestions. The factory unit can be had for $350 and then there's less expensive units, Koyo, Spectra, etc.
Cost isn't a factor, just quality and fitment.
TIA

Got a Koyo and have had no problems. Will sit in traffic with A/C and all on, upgraded turbo, no heat issues.

I made my own brackets out of angled aluminum and got some bolts from fastenal. about $30 and an afternoon to make the brackets.

There's better cooling units out there than the Koyo N-Flow, but at the cost of ease of fitment. For most of us, the N-Flow is the way to go.

Thanks guys, but just another quick question. See Koyo states that the side stock frames need to be changed over, the OEM fan shroud will still be retained, but will the factory air intake that runs across the top of the rad still be able to be used?

The car is only slightly modified (12PSI) so I want to retain the "stock" look. At one time years ago, had an Apex intake on the car for maybe 2 days and didn't like the noise, so went back to the stock system which I want to retain. Actually the Apexi is still in the garage with all the other parts that the wife keeps complaining about when she "visits" the back garage.

Thanks again

I still have the stock intake system on my car. You can bolt up the factory shroud on as well and it fits. The thing you have to take into account with the koyo is that it is thicker and taller than the factory radiator. That's why I made my own brackets. If you use the stock brackets, the radiator will sit upwards and toward the rear of the car, or at least on mine it did. It needed lowered about an 1.5", and brought forward about 3/4" for the shroud to fit reasonably.

On mine there was about 3" of radiator sticking out the bottom that the shroud won't cover. That hangs out around the steering rack, but not low enough to be an issue if you hit a possum.

Its not a perfect fit, but all it takes is some hand tools to remedy

Thanks, appreciate the information.
