Air filter test

This is a bunch of bull. Isnt AC DELCO partially owned by GM? Wouldnt GM benefit from the marketing of AC DELCO filters?
this test was biased. Im sorry but its the truth. they were testing it to find the best filter for a duramax (GM) its a sales pitch for AC DELCO. If we got any any of those other filters site they would have way different results.
If AC DELCO didnt place first in all of the readings then I would be more apt to believe it

I don't disagree with the statements made but one must be very careful spouting off about testing methods and so forth.
Things to consider: ISO testing is only a method to discribe how something was tested and if the results can be tracked and repeated. ISO = International Standards Organization. I have written many a ISO proceedure. They don't come from the scientific community (unless you need it to). The method of testing that should be considered more accurate and industry standard would be something from SAE. I know I have the number somewhere but I can't find it right now.
Next, if you read it carefully the results are not for the same filters for the same testing. The part number for example of the AFE changes to suit the results. This is the same for the K&N.
Further, remember that in a diesel air + fuel - waste = power. It is a simple equation. The concern one should have is that how clean is that air, how clean is the fuel, what are my waste factors and how much power is being added as a result. It is a trade off with performance filters.
I have run K&N in my Dodge as well as the current unit an AFE non-PG7 w/ a prefilter and the intake tube at the compressor is so clean you could eat off it.
I would not knock someone for using the OEM drop in filter but I would question anyone using an aftermarket filter that isn't properly cared for.
Just my thoughts.

still. to have your filter come out ahead in every bit of testing is kind of far fetched
