If all you want is a couple horsepower in a certain rpm range, I feel it is not worth it. I do recommend swiching the cooling fan to the double electric set-up. If you are looking for more power in the future i.e. turbo, all of that stuff is going to need replacement piping and routing, there's an intercooler you got to fit in - the fan eliminates a lot of drag as it is driven by the crank.

If you're not planning on getting turbo, and you like the way they look. Go for it. I've had them on other cars and like them.
