I have a dyi intake with a kn 4 by 9" filter on it. would i be better upgrading to a napa #6637 filter or something like that. or is there another filter you would recommend?

i also have a spectre 10" high flow filter, would that be the same as a k&n?

Anything is better than a K&N

I wouldn't use the spectre
