Intercooler/Charge-cooler Advice (2015 S4)

Gurus,

Seeking your expert advice/experiences on intercoolers/charge coolers (apologies if I’m not using the correct terminology) for a 2015 S4. A little context as to what I’m hoping to achieve – basically just the same “feel”/response as we get when driving in nice cold, crisp weather. I’m not a 1/4 mile nor track guy (may go once or twice) and the car is a daily driver at times caught in brutal traffic (mixed highway and city).

I’ve been researching and it appears that AMS, AWE, and APR have setups with their data posted etc. These systems look to have 3 components – the cooler itself, a larger reservoir for the coolant, and a “pump”. Question – to balance cost/benefit to what I’m trying to achieve, do you think all 3 are required or just specific parts? Obviously the full system is best, but if I were trying to trade-off some benefit to keep the cost lower, which parts would you recommend?

Thanks for your time and looking forward to your input!
