HE set-ups

Both Renntech and evosport, perhaps others, offer packages.
I know that colder air is denser air hence more hp. Call me old school, but such a system makes sense to me as a first step before pulleys and ECU work.
Are there any downsides to the sc cooler solution besides high price? If there are extra cooler radiators why is a high flow pump required? If one drives the car in winter is there a possibility of coolant freezing? Are phenolic spacers required?
I hope I can get some good feedback based on engineering facts. I know when I increased the density and speed of intake air into a normally aspirated engine it did improve HP and drivability.

I just got my car back from Eurocharged and just like you stated, the first mod i was going to to was the HE. I was told from them that where I live the stock HE would be sufficent and we just put the larger pump on ! I just did all of this you can see in my signature. It runs great, I haven't had any issues !

Dumb question
what sort of coolant does the sc system use? Anti freeze or water or some arcane MB juice?
