This. And here's my $.02 on making the choice--MAKE the choice, don't let something break and get backed into a corner. Either BP your stock intercooler now for $90 or pick up a reasonably priced aftermarket option from the forum (usually $400-500). If you blow you endtanks and have to buy something new it's gonna run you $650 or more plus the PITA of not having a working vehicle until you are able to get the part in.
EDIT: I'm obviously biased here, but I honestly try not to tell people what decision to make for their own needs and their own car. I will definitely agree with others though that if it is in your budget you should think seriously about upgrading the stock intercooler in one way or another.
