I was surfing the net tonight and happen to find this neat little article. Thought I would post it here for some informative reading.

very interesting...i have gotten purolator stuff from advanced and it looks like they even do better than k&n....i found a baldwin dealer right up the street though, since its time for a new filter anyway....neat study...just goes to show you that just cause everyone swares by a brand doesn't mean its that good...

great article.......which also proves that you need to be really carefull with your choice of air filters....and it also proved that the aftermarkets DONT filter better than the factory filer.........great read.......Marc

i never have cared for the k@n filters. i like to keep clean air coming in the engine, even if it restricts the airflow a little.

U da man.....i been trying to preach that stuff for a long time...it even proves that AFE and the better of the aftermarkets sacravice some filtration for airflow......but at least they dont just let rocks through like the K&N....lol.....the bottom line with filtration is this....and i promise....i will TRY to not preach this again.....lol...but you know i will........

there is only 2 ways to get more air through a filter...........

increace surface area.....most importantly USABLE surface area...cause lots and lots of pleats are not usable cause they are packed too closely..........but filters like the napa filter for the 7.3.....that filter still filters very well...but it has much more usable surface area thant he stock filter....that is a gain.......

then you have the k&n style gain....larger holes=more air....but larger holes=less filtration..........Marc

Ever since I purchased my PSD, I was told AFE, AFE, AFE, but that report seems to say something different.

Also.... (worried) wonder if AC Delco makes filters for a Banshee..... currently running K&N's with outerwears.
