GN vs. TTA Intercooler?

[PhillyD]

Is there any difference between the two? How can someone tell visually?

Thanks

The TTA/GNX intercooler had a higher fin count per inch than the stock GN intercooler. The overall dimensions were the same.

So 12 fins/inch compared to 10 fins/inch on GN

Also the Intercooler tags are different if it is still on it. Intercooler Tags

I was talking with our local GN expert Richard Clark last month about this and he said that there is variation within the same inter cooler when trying to count the fins in a 1" segment. The best way to tell it to count the entire row. A GN has 42, TTA 54, and GNX 64. I have not had a chance to count mine yet, but Richard has 4 or 5 GNX's and more GN's than I can count.
