[This followup was posted to  and a copy was sent to the cited author.]In article ,     snipped-for-privacy@mediacreati  K&N filters and similar will do little for most modern engines. Also, they use a coating of oil to trap dirt. If you are not careful, that oil can get sucked into the intake and coat or damage some sensors, such as the MAF (Mass Air Flow sensor). Just use a quality filter and change it as scheduled.  TornadoAir and similar are 100% snake oil. MAYBE with an ancient, carburetor engine it could help. With most fuel-injected engines, it can screw up the air flow and confuse the MAF.  Just use quality oil, of the correct viscosity range, of the correct or newer API rating, and change it as scheduled.
