I always liked the cowl induction for the older models. My friend has one but he has i think it's like the "turbo" hood? With the two little inlets on it. It's nice.
I would go with either the Cervini's 2.5 inch or 4 inch cowl hood or I would get the "Heat Extractor" that Cervini's sells and it is just like the stock 03/04 Cobra hood. I like the Heat Extractor a lot but it is expensive. Cervini's in my opinion makes the best fitting and looking hoods out there.
