I'd be interested in picking this intake up for the price and having it dyno'd before and after. If there are no increase in performance, take it back for a refund as it clearly states "this CAI kit gives a typical increase in torque of around 5% with an airflow increase of approximately 30% over the factory system" could also log air flow and see if there's a genuine 30% increase or not... tempted... but with the cost of the dynos, I may as well buy something with proven gains to begin with
