What looks like a low mounted filter could also be a turbine outlet.
It looks like there is a curved heatshield on one side of it. What could be a wastegate actuator on the otherside. And I see some bolts on either side that might be "downpipe" bolts.
Edit....It also looks like it could be the MAF on the compressor inlet. I think I see a "MAF electrical box" on the side of it.
