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.
