K&n cai??
 

Will K&N 57-2572 work/ fit on my 2008 4.6 V8 F-150?
any help is appreciated

Why? The stock intake is a cold air intake. Do a Gotts mod if you want.

I put something like that on my '12 F250 w/6.2 and made the intake too noisy, and now sits on my shelf. I know that is not what you asked...That being said, I do use the K&N replacement filter, and have had great luck with that on all my vehicles.
