I haven't done any of this myself, so I don't know.
But I am sure I have read about it previously here on this forum;
"
What may work better for these is getting a B-series airbox ... they fit from my understanding ... and the F6 lower snorkel .... which will pull clean/cold air from around your headlights in an AU XR. You'd get more benefit from this than the over-rad snorkel."
Maybe try searching amongst these;
