Particles....Oil and Air...
Discussion
A general question really.
Theres lot's of Air filters/induction kits available. But the bad news (from some quarters) is that they let more/larger "dust 'n stuff" particles through. I'd like to bet some are better than others.
Now this obviously applies to any filter for anything. Significantly the oil filter....some oil filters have to be better than others...
Any damage done by poor quality filters will surely happen over 50,000 or 60,000 miles. Now we dont all have the time to try doing 50,000 miles trying a standard Air filter and then 50,000 miles with the K&N induction kit.
So does anybody publish figures for the quality of their oil or air filters? Particle sizes etc?

i would imagine k&n/pipercross will be better at stopping fine dust getting through if only because you put oil in them, the oil obviously attracts the fine dust and keeps in on the outside of the filter. im not sure of spefics tho. other than that they obviously use better technology than the usual paper rubish most manufacturers use. hence they are more expensive.
I know of no performance filter maunfacturers who claim filtration size of their filters. I do know that Mann filters market their Micro Top filters which they claim filter about twice as well as 'Premium' filters from other brands. This only relates to oil filters though.
It should be noted however, that the wet or oiled filters (air filters),filter progressively smaller particles as they become dirty. That explains why many K&N types start off noisy and quieten through use. In my opinion, thses filters would probably reach the same filtration quality as the original filter if not cleaned too much. After cleaning, though, the particle size which could pass through the filter would be greater until the 'gravel bed effect' was able to improve filtration levels.
