The OEM air scoop works in conjunction with our sealed airbox to seamlesly force cold air into our air intake system. Air then flows through our 3.5" high flow air filter, which utilizes an inverted cone design for maximum engine breathing. Our 3.5" CNC mandrel bent aluminum intake pipe allows for smooth entry of cold air directly into the the engine, minimizing turbulence from unnecessary connections. All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race inspired sound. Peak power gains range from 10-15HP on an otherwise stock vehicle. We recommend disabling your Soundaktor (noise amplifier) to fully enjoy the true sound of your motor and remove excessive drone caused by the device.
