Yep +1 Farkle!. Google BMW F30 intercooler installation in YouTube.
It's basically about 2 dozen 8mm bolt/screws to drop the front splash panel and 2 T(something) wrench/sockets to undo the intercooer mounting. Use a 2 flat-head screwdrivers to undo the intercooler couplings.
Maybe an hour TOPs to pull the original and install a new one. It's laughably easy.
