I wish this was available back when I purchased my w/a intercooler... And finally something like this has been made..

wow thats not bad at all, whers the heat exchanger going though, or do you have to make your own etc etc

You would have to make your own
 
Not a bad idea but a couple of things I would be concerned about are
The extra weight if it only uses the factory mounting points. Ive see them crack from just a a2a IC
Its quite expensive. Cheek out frozenboost (not a bolt in option though)
Its EMS powered

Also I'd wager its just a standard A2A core with a water jacket. The better W2A coolers are a different core design based on the different heat transfer of water. Since you still need to sort out the heat exchanger, its not really a bolt in option, and therefore pretty expensive.
 
When I get around to sorting out a W2A setup, I WANT to replace the piping. With a 3SGE sidefeed manifold and the cooler on the passenger side you could really get the lengths down.
