From all my research on various platforms, GTR forums deep dived this issue and all concluded that Garrett makes the best cores for intercoolers. Their fin count and placement which is staggered I believe provides the best cooling possible. I know that AMS uses Garrett cores and then welds on CNC end tanks, most companies source their cores from China and then just weld on their own end tanks, the intercooler core is where the money is spent. Some cores from China are decent, some are *****. I had a AMS race intercooler on Alpha 9 GTR and it was pushing 800 whp and my intake temps were well within safe limits, different platform I know but just show's the quality of the cores. I also live in Northern Canada and I see people asking about cold weather climate and condensation issues. Really there are no issues with condensation with the cooler weather because as temperatures drop, humidity drops off drastically as well so you are drawing in less moisture into the engine. I also see no benefit to the intercooler intake shrouds, really it should be as little restriction possible for best performance. I do understand why the shrouds are placed in front of the upper rad area though because it aids in maintaining temps for initial startups in extreme cold weather to help warm up time and for temps when highway driving in temps like -40C that we see up here. Believe it or not with my diesel truck I actually have to ziptie cardboard to the front grille to cover it up when we reach minus 30C or the truck won't be able to get up to normal operating temperature. I asked Winfield recently on what intercooler he prefers and he said they are all very good but if you plan on doing turbos you will need one of the upper intercooler setups. I'd like to buy the AMS but they only do the stock location IC, the COBB is proven on Winfields goosetuned Gen 2 raptor with 700whp garrett turbo setup. So for max performance probably Cobb upper IC setup and if going for stock IC location I would pick AMS. My only gripe about the Cobb, and its purely aesthetic, the rounded upper edges just dont look as good to me. I really like the sharp lines of the ADD and SVC IC's. I'd really like to find some better info on comparisons between the cobb upper IC and the SVC or ADD IC's.
