Steeda and SCT collaborated to put together a well-designed system. Notice how the Steeda cold-air kit includes an airscoop that retains the stock cold-air duct behind the front bumper. The use of this feature ensures the absolute lowest air-intake temperature possible for maximum power. In addition, the Steeda air-inlet tube accepts the stock Induction Sound Tube. Although that doesn't add any power, it sure provides driving enjoyment.
