Just came in from Mustangworld.com, and saw a how-to on removing a piece of rubber that extends from the stock air box to the side of the engine compartment frame. And then I ran downstairs only to find out that my Duratec 2.5 V6 also has a very similar piece. I was wondering if any CEGer has tried this modification already, it's supposed to more that double the size of the opening in which the intake has to work with.
