I have seen that report before, and like I said before, I STILL think that a paper filter is the way to go on turbo diesel engines. That report just backs up my thoughts.
Good morning,
First, a little background. My name is Karl Kolbus, and I have been
involved in motorsports for 30+ years and have used K&N filters on both
racecars and personal vehicles. I'm also a full-time RVer, and am on the
staff of the RV Forum at RVFORUM <http://www.rvforum.net>, with a
membership of over eleven thousand; some full-timers, some part-timers,
and some wannabees. Our purpose is, first and foremost, to assist other
RVers with questions of a technical nature. As such, you can well
imagine that there are many questions about engine performance and
maintenance related issues, and the effectiveness of K&N reusable filter
has come up more than once.
There is currently a K&N debate going on HERE
<http://www.rvforum.net/SMF_forum/index.php?topic=15347.0;topicseen>,
and one member posted a link to what appears to be a comprehensive test
of various filters and their efficacy. It can be found HERE
<http://home.stny.rr.com/jbplock/ISO5011/SPICER.htm> . After reading it,quite frankly, K&N doesn't fare well in comparison to most others
tested. As you can see from my posts on this topic, I've been a staunch
supporter of K&N, but now find myself in the position of not being able
to refute these test results, and it's not a comfortable one.
If K&N would care to respond and/or refute these tests or provide test
data of your own, I would make sure your response is posted
appropriately. I sincerely hope you take this opportunity seriously. I
will post a message today that you have been contacted and that I'm
awaiting your reply.
Regards,
Karl Kolbus

Personally, having been given the opportunity to refute this report with any empirical data and not doing so, I would have to say "This myth is busted".
That statement is both misleading and, well, misleading. Any engine has enough sucker-power to pull in whatever is in its' path, save for whatever protection against large rocks and 2 X 4's the filter may provide. Turbocharging has absolutely nothing to do with it, nor does it make a difference.What I DO believe is that a turbo charged diesel engine IS strong enough to pull the oil right on through a heavily oiled K&N filter.
And that means... what?Keep in mind that I'm running a K&N in my Ram as well as 2 Harleys.

If your turbo was not present, your diesel motor would have almost no power. You would have a hard time starting off from a dead stop, and probably could not achieve highway speeds. And forget about towing anything....lol.
.... we'll add it to our Glossary section.
