I had alot of ppl tell me it was worth it. Personally, I didnt feel any gains at all. Even in the High Performance Ford Focus book I just bought, it says that the differece between the two is very minimal. You have to either get a dual runner intake manifold which will make a bit of a difference or fab up the stock Ztec one by port-matching. My next step is to get the dual runner manifold from an SVT. So basically, it up to you........My two cents is I didnt notice a difference, so it wasnt worth it to me.
