I've installed a few CAI systems on naturally asperated car engines with pretty fair results. I have never done one on a turbocharged car-- I'm certainly no expert, but I have always felt you will get more bang for the buck with a more efficient
intercooler . . . most so-called CAIs for turbo engines fit in the category of
audio-visual mods: They
look cool and
sound great! Most twin-turbo V6 cars I've owned came stock with a pretty good COLD air intake system-- sometimes a filter change can get more air, if you don't mind trading
clean for
flow.
The
Takeda discussed above looks very good!
