The cold air intake system increases throttle response for Chevy/GMC. By delivering cooler, denser air to the cylinders, the engine receives more oxygen, resulting in increased power and torque. The kit includes a high quality, reusable air filter. Installation of the air intake is fairly simple, with instructions and support provided by Rough Country. This air intake is a great way to give your pickup truck more power and dynamics when accelerating by cooling the air at the intake.
