Subaru has their own product to combat this called "Upper Engine Cleaner", you spray half the can into a vacuum hose on the inlet manifold, start it up and it chugs and churns out massive amounts of white smoke from the exhaust, keep the revs up and spray the rest of the can in the hose and it cleans up the inlet manifold and carbon build up elsewhere.

Magic stuff
