All depends how much power you want to run really and ultimately what your budget is.
Many people are running that intercooler on K03S applications, circa 230-240 BHP. That said, I haven't seen any logs to comment myself
I do think too many people underestimate the importance of a good intercooler though and what goes into making one - it's not all about core sizes and intake temps, there's much more too it than that.
At the very least I'd have a read through http://www.fromsteve.net/tech/Intercooler-Sizing-Design-and-Implementation
