Did you waste your money on K&N?

This is similair to the oil filter argument. A filter that it advertised as one that will remove particles down to twenty microns, That is fine but if you read up on that particles that small have little or no effect on Engine wear anyways. plus they have a large enough pressure drop that could open the filter by-pass. I run K&N Air filters For the performance rating for years and never had any problems. This is basicly the same argument, how small of particles do you need to catch to prevent motor Damage with out having a large Air flow restriction across the filter

I think the guy has Tom McHill that used to be the auto writer for Mechanix Illustrated years ago that claimed any dust smaller than a grain of sand would likely be incinerated in the high temparatures produced during combustion,and also be sucked in and blown out the exhaust so quickly it would not have much of a chance of causing harm,that it probably would stay trapped in the "airstream" going thru the heads--he ran several cars with nothing more than doubled up window screen on his carbs,and he didnt see much if any ill effects--but that wasnt out in the arizona sand either....I ran many mini bike and go kart motors with no air cleaner off road for a long time--most if the ones that burned oil already did before I took the filters off(no filter made it run faster,more power,and easier to start by "choking" it by covering up the carb with your palm
...I do like filtered air going into my trucks motors though--I took off the cheap edelbrock triangle air cleaner when I noticed the foam is pretty skimpy on it,several places had big holes that had probably gotten sucked into the engine--I wonder if thats what helped break the #6 piston in my C10's 250 six..Hmm.

Those silt beds near El Currenta ar notorious for killing engines. The stuff is the consistancy of flour, and ingesting some of it is about like ingesting lapping compound.

I think a distinction needs to be made btwn what is good enough for a streeter and what works off road. I see a huge difference btwn the two. Very few tests or Authors consider off road use. As to the mag writers promoting K&N filters etc., WHY are you still reading that trash?
