I started looking around the web. Found a few articles. K&Ns look suspect, especially among the Porsche crowd. Bummer as I have 2 vehicles with K&Ns. Maybe its back to OEM filter time.

I don't think they underestimate their own product with their numbers, but their numbers are well below those of paper filters.
If the data actually exixts(I'm not saying it doesn't) please share it with us.
If you will visit my gallery and look at the second Blackstone report that I got yesterday, you will see that the silicone sample in my oil was slightly more than half the norm for this engine. This truck sits and idles constantly on construction sites where the clouds of dust are thick. My data (real published data) proves that the K&N FIPK works on my truck, in both filtering and air flow. I have no data on ordinary stock replacement filters.

Verify your own vehicles health by having the oil tested at Blackstone. This is the ONLY way you can prove for sure that the products you are using are working. It costs $21.52 per test. This is a small price to pay to prove to yourself that most of what you read on these threads is bunk. Don't waste your money by throwing away perfectly good air cleaners.

JackFlack: Sorry, didn't mean to repeat your link.
Chocktaw Bob: You are right in that the best bet is to test your own vehicle. And yes, we have to be careful in trying to separate fact from fiction on the web.
All: There is a HUGE discussion on the Chevy diesel forum regarding some air filter tests that were recently done. The K&N did not look very good, but it is hard for me to believe it was as bad as they indicated. A guy from K&N is interacting with the guy that initiated the testing, which was supposedly done by an independent lab. I will be following this discussion for sure.

All kinds of people promote one product over another for their own reasons. If they don't have a financial tie to one product or another, they get involved in the discussion cause it makes them feel big or smart or both.
I use K&Ns because I have proved them on the dyno and with Blackstone tests. Any discussion after the filters are proven is a waste of time.

Not that we don't trust you. But you know there is a large difference between a Pinto or Nova air cleaner and a 6.0 FIPK.
You know that you can't correlate test data between different products. You have to have actual data, uncorrupted.

I agree, you need to compare independant test data. The problem is most "independant tests" are not really independant. They are payed for by the company that posts them. The problem with most tests performed by amateurs is that they are not done very scientifically. I wouldn't think any company would perform a truly independant test because who would pay for it?
Anyway, that's why we have these fun debates from time to time. We may not ever have a true independant test.
Did I mention that FTE has a search function?

Fellowship of diesel owners set aside....here is the deal on K&N filters from my personal experiance...yes i can't spell. I had the stock filter on my truck....no dust in the intake tube. Put a K&N fiilter on....fine layer of dust in the intake tube. It was factory oiled...cleaned and reinstalled...still dust in the intake tube. That my friends is DIRT being passed through the filter. Think of what that does to an engine. All these independent studies don't mean boo in the real world. If you have a 1000 hp engine and you are going to rebuild it every couple of months, fine...put a K&N on it. Thats reserved for drag cars that make runs for 10 seconds or under, not something you drive everyday. If you think that putting it on your daily driver in hopes of making big horsepower, forget it. Its a pipe dream, don't waste your time or money. At best it might make a little more noise. For those that can remember. chrome and noise does not mean it's fast

I just installed an AIRAID intake on my 6.0, hoping to get a little better than my current 11 mpg. I don't know if the mileage is going to be better but my air conditioning sure works better. I can't explain why it works better,(mechanically challenged), but since it's been over 100 degrees I'm just glad it does.
