Okay, agreed- about the K&N air filter. The dirtier it gets, the more dirt it removes from the air. AND-read the back of the package- using cotton gauze and oil is a BETTER method of filtering that dry paper.
I have NO experience with K&N oil fliters.
BUT- I do use Mobil 1 filters, and have been pleased with the oil coloring and smell at a five thou mile change interval.
I have yet to send any off to a lab to have it checked- but that's a good idea.
Also, Motorcraft filters are very good- and much cheaper. But, there was the restriction issue.
Speaking of that independant tester, where did his website go? I have been visiting it for a while, like maybe a year, everytime I wanted to review his info, and now it is GONE..... hmmmm...
So, stick with Motorcraft or Mobil 1.
