I need help finding this piece. I have looked everywhere but don’t know what it’s called. Passenger side covering the side of the fuse box

 

Not sure but you only have one air-box? I think with the larger engines they use dual air box setups and the second one would be installed in that area?
Just guessing because I don't know as I have never seen a 4 cylinder Jaguar.

Yep, only one air intake / airbox / filter on the Ingenium I4 petrol.
Same with all the diesel Jags, 3.0 V6, I4 2.2 and I4 2.0.
As opposed to all the 4.2 V8, 3.0 V6 AJ126 and 5.0 V8 AJ133 which all have dual intakes and filters.
