K&N Air filter vs Paper: Test results
I wanted to see for myself what the difference was between K&N Air filter vs Paper (NAPA). So here's what I did. I ran each filter about 5500 miles then sampled the oil (Mobil 1 10w30) and sent it to a lab for analysis. Here's the particle count results:
K&N SIZE NUMBER/ML 4 um 37960 6 um 1449 14 um 139 21 um 33 38 um 20 70 um 13 ISO 11171 CODE: 22/18/14 Paper: SIZE NUMBER/ML 4 um 419920 6 um 4860 14 um 113 21 um 75 38 um 45 70 um 30 ISO 11171 CODE: 23/19/14 If I'm reading this right, the paper filter (which actually had a few hundred less miles on it) was dirtier! Same truck, same driving conditions. Only difference: I was using a Delco oil filter on the K&N and a NAPA Gold oil filter with the paper. I was really suprised! I expected the opposite results. So it looks like the K&N is superior- at least on my truck. What say you?
