I didn't get a proper look at these yesterday, though Scott mentioned it while I was taking photos, kind of tuned out behind the lens.
I wouldn't expect them to be intercoolers, more likely they are some oil cooler setup as has been mentioned.
I am pretty sure the intercooler setup on the gen3 TSI is still much like the previous generations, where, Water Rad, air con and intercooler are sandwiched together behind front grille.
It's quite interesting how similar though the new gen3 1.8TSI engine is to the gen3 2.0TSI, almost identical arrangement, only real visual differences are Cupra on engine cover, and Cupra's washer bottle is on the near side raised, where as the 1.8TSI has its water bottle sunken into the offside front wing. Most likely because of the aforementioned extra oil coolers on the Cupra.
Obviously totally different animals in performance, but surprisingly similar layout despite displacement and cc differences.
