4" Intake Pipe/Filter for SR Top Mount Turbo Setup

As title states, looking for a 4" intake pipe +/- air filter for my new turbo setup.

I realize I could probably go out and just buy some 4" pipe and make it work, but would like to see if anyone has something cost-effective that would work.

Needs to be 4" all the way through. No 3" to 4", etc.

Might also be interested in just an external venturi, or even just a filter that will fit on the end of the turbo…

PM for fastest response.

Thanks,
Dan.
