Interesting K&N test data

[Texas Diesel]

I had two K&N air filters (with greasy lips), my silicon (dirt) levels went from 5PPM (OEM paper filter) to 34PPM (K&N).



Both K&N's now reside in the landfill.

Interesting to note that the paper filters did the best overall. Of the oiled type, AFE was best.

Interesting to say the least. One thing I didnt see mentioned, were all the filters factory replacement type (like for the stock box) or were they the complete systems?

seems like a Advertizement for AC Delco... . hey are the best at everything..... Right... .

I wonder why folks running UNI filters on our Rams... Cone dual stage are getting 6-7 PPM just like the paper brick for the factory air box? And thats with 20K on the filters and oil.



I agree its an advertisement. Its a well tailored report. Was it done on a ram? no Was it done by and for someone that sells a certain brand? yes.



Some of the panel filters leak around the edges real bad. Thats been known for over a decade now.

Amazing. If the test data doesnt coinside with your opinion, then the test data must be flawed or biased.



Absolutely amazing.

If you read the test data and the results people have with filters on Ram diesels... it would make one wonder how they got those numbers when the oil analysis of hundreds of trucks fail to match their numbers in the test data. These trucks are averaging far more miles then the test bed too.



That is what I find amazing. These folks with these trucks must all be lying then. :-{} The labs doing the oil analysis are lying too. AMAZING.

What I found was amazing was the oil and grit that was all over my turbo blades about 5k miles after installing a brand new factory oiled K&N re-0880. I was amazingly PO'd, and I didnt need an oil analysis to know that was a very bad thing.

I would find it really amazing if a manufacturer ever published tests results that didn't say their product was way better than any competition.

Just curious, where did you read that?

 

[macdaddy]

K&N's are for street use only, drag racing etc. Always use a 7 micron filter at least such as the AFE progard 7 for all other applications.

I will elaborate on this some. First off to clarify, the test is not done with a Cummins Ram correct?

A vendor that is at DTR was posting the report everytime anyone asked about filters. He claimed the paper was done by a valued colleague.



Secondly, I switched from K&N filters to the afe for the same reason pointed out here... dirt getting past. The pleats became smaller, the media was thinner etc etc. Over time their quality slipped from what was a good filter at the start. For awhile we had great success with the afe and then encountered several reasons and issues with the filter, supply and other concerns not directly related to afe. This is when I sought out a filter that would not only filter well but work well whether it was dirty or not. We elected to go with a dual layer filter for optimum filtration. I researched the UNI filters and oil analysis from dirt bikes, BAJA trucks and then with the Cummins in the Ram trucks. I guess the test is good for what it has. However, more often then not it becomes an overall branding that certain brands of filters on the Ram are not safe.



I would be the first to can my product if I had a problem with filtration that could not be resolved with a different and/or better brand of filter that is different then the competitors.



After running 20K plus miles on two single stage 9" filters on dusty roads, rain , snow, salt and temps from 90 to -40, I fully expected a much higher reading of silicon with the two UNI filters I had in there. They weren't maintained at all and were dry upon inspection. My oil results never exceeded 7 ppm of silicon on any of the tests. Not bad at all.

Pretty amazing huh? I will deal apples to apples and I still await one of these companies capable of testing to contact me and put my filters in one of these tests with our engines.

I post that test all the time. Have been doing so for over a year now. I found it over at thedieselplace.com. The tests were done on a Duramax and were part of an experiment performed by some of the members there.



I felt the test was legitimate enough to warrant a bookmark, and like I said I refer to it frequently. I do not work in the filtration industry.

Scotty,



did i get a good afe on my scotty3 or a crappy one?

Very few if any of the turds got shipped. I was able to see the flaws before they went out. rubber not fitting on the filter end, pleats un even, etc etc.

It would be very apparent if you got a dud.
