By no means am I an expert, barely a novice if that, I'd say you don't want to do that...if I understand you right. What you will be doing is adding filters up front going through the same diameter pipe running to existing filters. I'd think this would just limit the amount of air even more so.

Even if it is a bit bigger, you will still have limited airflow because of the added filters and the point where the pipe reduces. I believe that is why all of the after market CAI's bypass the stock CAI.



But I'm sure one of these more knowledgeable ones will let us know.
