AEM Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, AEM-21-862C

<p>AEM 21-862C Cold Air Intake System. Aluminum Gunmetal Gray Cold Air Intake System (21-862C) by AEM. To deliver cooler air to the engine, this air intake system places the air filter outside the engine compartment. Cooler air is denser than warm air and so contains more oxygen, which results in better combustion and more power. It is a well known fact that cooler air is denser and contains more oxygen. Cooler engine air inlet temperatures result in more power. But your stock, restrictive engine air intake system delivers hot air from the engine compartment! The answer to this dilemma is to install an AEM Cold Air Intake system. AEM starts by positioning its high-flow Dryflow air filter outside the engine compartment, to draw in the coolest air possible. AEM performs extensive temperature testing for each application to determine the best filter location. But that not the end of the story. The Dryflow air filter is connected to the engine air intake by an aluminum tube tuned in length and diameter to match the engine's intake resonance.</p>
