K&N Air filter testing-pass 18x more dirt

Postby SunWizard » Fri May 15, 2009 9:45 am

I found an interesting site where some duramax owners tested a wide variety of air filters against each other using very good methods.

After reading this, I got rid of the K&N reusable filter that came on my truck and my car:
Compared to the stock paper filter, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt.

Thanks for the info it matches what I've read on other forums.
The K&N only works in some applications, motorcycles i think.
