    Is there any difference between AFE PRO 5R and the K&N Air filters. Both oiled cotton gauze. The K&N is said to pass too much dirt. I can't find any info on the AFE PRO 5R. Anyone Know?

    i do not believe that a properly treated K&N filter will prove to NOT filter efficiently and safely in the average driving conditions. tests can be deceiving because certain sizes of contaminants are way less harmful to engines than others. it is all about micron size with these things.

    that said, i am not sure if i would necessarily use it in extremely dusty conditions, etc. that is because those tiny pieces that don't hurt here and there probably can hurt in volume. for such uses, i'd consider the 7 layer filter AFE sells, a powercore filter from donaldson or one of the sexy filters from amsoil that claim ultimate filtration.

    i'd be curious to know if K&N uses a progressively finer gauze with their layers like AFE does with their 5R.

    one thing that pisses me off about AFE is they don't even use uniform test conditions and measurements between their own filters! one will be at 1" of water, another will be measured at 1.5" of water. wtf.
