There is no advantage. If you were go with the $275 dollar one? You are best off to get a WizAir CAI kit or for a little less the Thrasher CAI kit.
The difference between the the $45 one and the more expensive is that you are leaving your Filter suceptable to Engine heat sucking hot into your intake and hendering your performance. The CAI units will at least keep your air temps ambient to the outside air as compared to the higher temps inside your engine well.
I hope that explains a bit more for ya?
