The Porsche Macan has a unique air intake system that channels air from the front part of the car, into the hood, and ultimately into the air filter(s). This complex system is somewhat closed to the outside environment, and can heat up very quickly even under normal operating conditions. As intake temperatures increase, power can be lost.
The RADHAUS Cold Air Intake (CAI) helps to cool things down by collecting cooler air from the front grille, and forcing it into the OEM intake track. This system introduces a new air source directly in front of the car, which will capture more air when the car is moving.
