Need is a strong word. Dnyos on many different turbo cars (and IAT logging) show that even a stock IC will get super hot on the first run and it only gets worse from there. The truck will just pull power when that happens, so no you don't need it per se. Ford chose an intercooler that just barely gets the job done in the way most users drive the truck. In the manual it even states that in hot weather and pushing hard to NOT mount a license plate over the intercooler vent. I'm of the opinion that the Raptor IC is garbage, too small and in a bad location. Call me crazy.
