Was wondering what is the best cool air intake for a 2011 CTS 3.0L .. Thanks
3.0 and 3.6 are the same itemit says on k&n site they only make typhoon for 3.6l
I went with just replacing the OEM filter with a K/N filter on my 3.6...does the same as the aftermarket intake without spending $300.IMHO, cold air intakes are a waste money on our cars! The factory intake does a great job of being a cold air intake. Save your money and spend it on something else for your CTS. Obviously, there are some that will disagree with my opinion, but the majority here will agree with me. Do some searches on the topic here on this site.
12HP improvement, don't think so!
