The Cosworth CAI (if you can get it) modifies the overall inside diameter of the MAF housing which in turn changes the amount of air flowing into the engine vs. what the MAF "thinks" is going into the engine. The main reason I went with the FocusSport CAI is because it uses the factory MAF housing tube. The Cosworth relies on a baffle to slow down the air so that the volume being seen by the MAF is roughly what it sees when stock.
I had also heard that the inside diameter of the FIPK from K+N was different than the stock housing, but that's not proven by me nor did I do enough research into it at the time.
