Air filter, is there a difference...

[wrichards2005]

This is correct, I've had before, during, and after oil analysis done. I believed in K&N until seeing those results.

It was oiled correctly and everything?

Thats good to know, I guess, I'm running a K&N drop in.

amsoil foam oiled air filter

Anyone ever tested their oil while using an Amsoil foam air filter? That's what I have on my car and I'm wondering if anyone has test results on that.
