C'mon man....where does the compressor get it's air?? It's not the exaust gas that gets pumped back into the intake. The exaust gas is used to turn the turbine in which turns the compressor wheel that draws air from the ambient air inlet. A CAI on a turbo is completely legit and possible. You shouldn't flame this guy when you don't got your facts straight either. We can all learn something new without a wise-ass putting us down.
if your saying you need a filter and pipe for the turbo, you are wrong. like txhatch said, its there to keep rocks and shiit out of the turbine. go figure.
