AEM Cold Air Intake


When beginning the path of modification, one of the first modifications one may consider is a quality cold air intake system. The factory intake system is highly restrictive and leaves much room for improvement. The AEM Cold Air Intake System features a non-obstructed design that allows your engine to inhale a large volume of cool air to improve the throttle response, as well as the fuel economy. 

The AEM Cold Air Intake features a large intake filter that sends air through a smooth aluminum intake tube straight to the intake manifold with no turbulence. Expect to see improvements in the engine and throttle response, with an aggressive suction noise under acceleration.
