Not Ranked
Like I posted, going from the standard 1.8"tall paper filter to the 3" K&N (E-1963) made a world of a difference for mine and I'm only running a .030"over non-stroked 351W. You probably wouldn't convince me that you could have too much filter, so if you can fit the 3" or the 6" (E-1966) do it. Although to realistically use the 6" oval filter, you'd probably have a superhuge-stroked-bored-blown-mega inch motor that you wouldn't want to stand too close to otherwise you might get sucked in.
