Has anyone changed their Air Filter from K & N too Am soil Ea Air Filter and if so what was your experience between the two?

Did you notice any difference with the Amsoil Ea Air Filter over the K & N Air Filter or vice a versa?

I am looking to change from K & N Air Filter too Amsoil Ea Air Filter for the reason that I had to put a NEW AIR SENSOR on my 1999 For Ranger 2.5 4 CYL. , do to the fact that dirt or oil got on it and made it go bad.

As far as performance is, this is what I will have to see which one will gave me the best.

I am hoping that someone has the experience between the two first hand.

Ford would like me to go with the paper air filter.

 I can't speak for the Amsoil product, but the K&N filter that I have has been very good.  Either one would be a big improvement in airflow and performance over a paper filter.  I switched back to paper before turning in my lease (gave the K&N filter to a friend with the same model car) and could really feel the difference.  The paper filter seemed restrictive.

 im going with the k&n air filter with this one. most of my friends are using it and we didn't see any problem with it so far, especially with the cabin air filter. goodluck with your choice.
