I wasn't the one making the initial claim like you were, I came in after your claims and asked you to prove it, you haven't and all of your follow-up comments further proves to me you don't know what you are talking about. I find it terribly hypocritical of you to challenge others for proof when you haven't provided one iota yourself.
And honestly, I don't have to prove anything, but I will give you a sample, read this simple look at the restriction of certain air filters:
http://www.bolhuijo.com/airflowtest/index.html
This simple test shows that the K&N is more restrictive than the Mahle OEM paper filter.
And here is a BITOG one (along with the Spencer one above) that shows that they don't filter as well:

So, they don't filter as well and they don't even flow better, so what is the point?
Also, Jim Conforti (well know BMW tuner) did some testing comparing the K&N to stock paper filter, he found that he K&N allowed 200-300% more dirt than the paper filter and only gets worse as it loads up with dirt (while the paper filter got more efficient).
Here are some interesting comments from a Toyota Atlantic team member:

And how about this article from Autospeed:

And how about this one that shows the stock airbox is best:

I also have a private study done by a firm in the UK which clearly shows that OE paper filters filter better than K&N. I have personal dyno results too, but I see no point in sharing them with someone who hasn't provided anything to support their claims but rhetoric.

Where did I say that???
(me, looking back over the thread)
What I said was >>>
>>> ...most car engineers have designed more than
>>> sufficiently sized air boxes with large enough
>>> panel filters holding standard OE paper
>>> filters to flow more than enough air into the
>>> motor.
Which isn't at all saying they have developed the "perfect air intake system". Read it again, my comment was addressing the size of the panel filter only, that is only one component of the intake system.
My point is, the panel filter is not the bottleneck in the system. So, even if some other panel flowed 2% better than OE, it likely wouldn't matter as the bottleneck is usually somewhere else.
Have you checked out your entire intake system? What is the smallest point? Throttle body? Intake runners? Inlet/outlet to/from the airbox? How about the plastic portions of the intake? Have you compared them to the surface area of the panel filter?

Thanks for that revelation, and that has nothing to do with anything I said. But, you can upgrade your panel filter to anything you want. Matter of fact, you could redesign the panel to be five times bigger than stock. Do you think you will increase power with all other parts of the intake system remaining the same?

Actually, you can put anything you want on your car as can all the rest. As far as I am concerned, you can run without a filter if you like.
But, you won't see a K&N on one of my cars. And I have proof and studies backing up my comments, what do you have? Oh, that's right, nothing but K&N marketing. Good luck with that.
