Errr....if it had a split side intake plenum with two throttle bodies, I could see the potential. Since that's not true on this car, I can't see any possible advantage. A CAI will suit you better.

drill a hole under where the stock airbox is and run a duct OR run a pipe straight thru with the filter at the end. make sure to use a AEM bypass for water issues.

Making a dual from a single causes turbulence. Increasing diameters and segmenting piping is a science that will only work on a dyno .

Plus the airflow will be restricted to the diameter of the throttle body, if my memory serves me correctly.
