AFE has data on their site that a stock filter flows 355 CFM @ 1.5" H2O. And we have 2. There is no restriction there whatsoever. Incidentally K&N's flow data on their drop-in for this car is also 355 CFM lol.

AFE claims 7% better flow than OEM for their drop in dry filters. I went with these for the fact that I can clean and reuse. My OEM ones were quite dirty after 9500 miles. The drop ins will save me some $. I'm don't feel or expect any type of performance increase.
