We all have our "two cents". What you are saying is partially correct but the same on every single car ever produced and the theory of it "not working" is incorrect. You can use meth/water injection if you like, I've found them to be a hassle and extremely unreliable, even more so on something that is going to stay in boost when you are towing, the tank will drain quickly.This is still against the radiator on the back side? This wouldnt let much air flow go over the fins and you would have to match the radiator fins also or you would even have less air flow. No matter how big the IC is if you dont have air flow its going to get hot. I think this is why the manufacturer made a tin core cause its also sandwich to the radiator. At this point water/meth injection would be the best solution to keep intake air temp under control. Just my two cents.
