Godspeed IC's have become a very popular choice for the Z enthusiast. The problem was that nobody offered a duct set to channel air into these massive units. KK Engineering has developed a very lightweight set of aluminum ducts to help you get the most efficiency possible. They are designed to surround the whole area behind the factory IC opening and extend up to include the area behind the fog lights and turn signals. They fit fine with the fog lights and turn signals in place but allows the maximum ram air effect if you choose to remove the fog lights and/or modify the turn signals.
