standard r - yes
Box r - not without a good bit of work. I think guys have made it work with machining the adaptor spacer to thin it down, and running drop mounts or spacing k member down.
I'm running drop mounts and it would not fit a stocker. I remember another box intake that was supposed to fit, but my memory sucks, so I can't remember the name & I'm not even 100% certain.
I run a 2.5" cowl hood. I think the drop is something like 1.5"
edit: Reichard Racing Box upper is what I was thinking of. I doubt you'll find one, and even if you do, you might want to verify my memory before spending the money.
