Cold Air Kit

You can run a tube to in front of the radiator and behind the grill, but would also have to insulate the pipe from all the engine heat else it wouldn't be cold air, more fresh air. Scoops are a option or like others have posted. Might feel a little difference in the seat but nothing that big of a horse power jump, unless its a tuned intake specific to your engine, but that's dyno tuning to check size, length and routing. Its your car, do what ever you want, who cares what others think, if you want it and like it, that's all that matters.
