Default Re: Ineffective Air Cleaners

And while I have my pendant hat on, the passage of air through a air filter is only ineffective if it does not clean the air, i believe the question is about efficiency, which, given the external static pressure of a adequately designed automotive air intake system relative to the work done by a healthy air pump (engine) at 18" of vacuum, is insignificant.
Aftermarket air cleaners such as K & N pod filters are all about increased induction noise giving the impression of increased performance
