That is a big statement from you Gav.

I am pretty sure it will draw enough air through the factory single hole, if need be I have a chrome top plate that I can fit on instead and it can draw plenty of air then.
Also thinking of running a pipe from behind left hand headlight, pointing air filter snorkel toward that way (I have not painted housing or fitted sticker yet) and drawing air from infront of radiator.
