Default K$N filters

Interesting post I stumbled upon on the other forum. I do not make any claim here, as I do not know the subject well, I’m just providing some info for those who might want to think about it…

I've used K&N filters over the years too, and while the results you
cite are not contrary to my experience, I am concerned about
recommending these for everyday use in a passenger vehicle. I have
done oil analysis on every car on which I've used a K&N. On all 6
cars, this showed many times the amount of silica particles (airborne
dust) in the oil than when a paper filter was used. This means that
the K&N does not do as good of a job filtering the air, allowing more
dirt into your engine. You may very well experience increased engine
wear due to this, as your oil filter will not catch it all.

Notice that K&N does not advertise their product as offering "better
filtration", only as offfering "better flow". The K&N is a good
product for it's intended use, which was not originally long term use
in a passenger vehicle.

Let me clarify, Probably what is meant that K&N's don't filter better than the paper ones, which probably is true too...

i'm confused. here's what i'm thinking: K&N produces filters for both stock and aftermarket intakes.

for the stock boxes, the filter is located in the same box that goes over the throttle body. does a lot of dust travel through both tubes into the filter? i had a civic that had ~80K miles on it, and i recently opened up the airbox and the filter was surpriseingly almost all clean... air probably always carries the dust particles put why didn't a lot gather in my old civic?

hmmmm

i underedstand that a filterless aftermarket intake would be harmful though since its basically a single "straight" tube to the throttle body though.

I'M CONFUSED! help!

There is either the one you drop in your original filter box (it is flat)... OR you can buy an intake which looks like a pipe and a snow cone that sucks air. 2 things... I had the KN filter and took it out, makes ZERO difference on an LX... only a new intake made any change.
