What Is an AEM Cold Air Intake System?An AEM cold air intake system is specifically designed to increase the volume of cold air flowing into your engine as you drive. The thinking behind this is that cold air is much denser than warm air. Therefore, if there is more cold air in your engine, there is more air in general, which also means that there is more oxygen. A higher amount of oxygen present in a car engine increases the potency of combustion, which can increase the power and efficiency of your engine.

This increase in power will also help you conserve fuel and increase your fuel efficiency, saving you money at the gas station.
