Interesting air filter tests

Like that guy , kind of shows , u cant have ur cake and eat it too !
Yep Bob I agree either you can get performance or filtration. I cant believe how bad the k&n did in the particle testing. That honestly makes me very hesitant to ever use one. I always run a mopar filter I'd like to see he run a test using them. On my mountaineer I run motorcraft air and oil filters
Speaking of which I think it's time to change both in the mountaineer
