Air filter for 2003 2.3 pzev - Ford Forums

I wanted to put a KNN in this but there is no part listed from KNN. The manual tells me that this is a non replacable filter. Is there a KNN swap for this?
Is this factory filter any good?

What about a KNN kit? Worth it?

Your car has huge, high flow - 150K km life air filter. There are high flow KNN replacement and I instaled it once, but didn'd see any benefits of it.
Advice: Live it as is!
