Yes I agree I think fitting the original air box is the way forward. And it's only missing from the photo as I just removed it to investigate the snorkel.That rubbish air intake needs sorting. Recommend fitting a proper air box with paper element using either a defender one or a disco version, you may need to move other items like screen wash unit to do this. Also duct from wing top to heater fan is missing, as is will draw engine fumes into cab, not good.
