Like everyone else on here has said, adding an inter cooler to a stock system is not always advisable, especially in our climate. If you're running stock intake, exhaust, ECU, boost pressure etc there's no reason for a larger FMIC. Bits very common for larger intercoolers and piping to effectively drop you're boost pressure in a sense.
With my focus st (2.0L turbo) I am running stock intercooler and piping for it still. I've done a few bolt ons like cat less downpipe, intake, Cobb tunes etc. I'm running a stage 2 91 octane tune and about 22.5psi boost pressure (15psi stock). They recommend I have a larger intercooler for the setup, but while watching post-intercooler air temps there isn't a need for it as of right now. Driving around its just like 75 degrees. A full boost under load pull sees it jump to maybe 95 degrees. But even in the summer it didn't go over 100 really. If this was a Californian climate then it would be a whole different ball game.
