NAPA 6637 Air Filter
The filtering quality and efficiency will be second to none
But if all out performance it will be lacking a good bit
That filter is good for around 450cfm at 8" of depression iirc
It definitely won't let that compressor show even close to potential
As the restriction and depression level raises all it is doing is raising the pressure ratio of the compressor

Yup
The larger filter you talk about is around 650cfm at 8" IIRC, so yes not stellar
I have a twin turbo Cummins and I ran this larger filter. Quit a bit of depression amas I have the filter minder mounted
So I bought a larger AFE dry flow to try. Very compact for the flow potential
That breathed awesome but was not up to the task of actual filtering on a ride that is on gravel roads and dust. It showed fine dust on the inlet. I drop kicked that thing across the shop lol
I moved back to the bhaf and live with the restriction but get OEM filtering
I now use that old AFE on my car and that will keep up to a gt55 94mm mid upper 20psi and non difference with the filter on or off
Inna street car environment it filters well enough.
I'd never use a AFE, r2c, k&n ect on an harsh particulate environment though
