I contacted Avalon Motorsports in Denver about carbon cleaning. They quoted me $590 for labor + another $266 for gaskets, oil, filter, and BG fuel/air induction/throttle body cleaners.
This seems a bit expensive compared to the prices I'm reading in other threads. Anyone find a cheaper price locally??
