They do say 350cfm for the testing but Isn't this about the filter media filtration/airflow not the induction system? I wouldn't be changing the setup it would just be an easy replacement of the filter job so I'm more interested in the filter itself.
sure they are all within 3% in that one of 7 graphs I put up but what would that 3% add up to over 300-500,000km surely that would affect longevity?
