I installed the D3 CAI about 3 years ago and now at 60K+ miles on the CTS I am having issues with the engine. So far the dealer has claimed oil from the KN filter screwed up my MAF sensor and they also think it may be hampering the throttle body. Anyone have issues with D3s CAI? It has been on there for probably 40K miles and cleaned/recharged once in that time frame. It claims to only need recharging 50Kish miles.
I was talking to the mechanic (not service advisor) this morning and he told me they have had few after market CAI do this and it was the oil in them.
