Re: [A/S] tow vehicle choice

Before buying a K&N for a long lived engine like a Powerstroke 
you should do some research. If you trade often it don't matter 
much I guess.
If you look at test data available on the WWW (on sites not 
promotoing K&N) you will find the K&N only passes more air 
when clean. It also passes more dirt when clean. When it has 
been run for a while and has picked up some dirt it begins to 
filter better but the flow efficiency falls to that of paper filters.
Here is one site.

There are others but I don't have them bookmarked.

I run an Amsoil oiled foam filter it lasts forever and acutally 
cleans the air going to the engine. Second choice is paper. The 
rest is for race cars where running more than 500 miles don't 
matter.
Thats my opinion anyway.
