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.

What Are the Benefits of an AEM Intake System?

An AEM intake kit maximizes the amount of power you can get from your engine. This increase in power will also help you conserve fuel and increase your fuel efficiency, saving you money at the gas station. In a sense, an AEM intake system helps your car and engine “breathe” more efficiently, allowing it to reach its full potential.

Why Should I Choose an AEM Intake Kit?

AEM is regarded as one of the best aftermarket intake systems on the market, combining quality materials, cutting-edge technology and reliable design to help drivers around the globe improve the power of their engine.
