AEM Cold Air Intakes Are Designed to Make Power Safely With Cool Dense Air

The traditional AEM cold air intake (CAI) positions the Dryflow synthetic air filter inside of a wheel well, behind a headlight, or in front of the radiator to provide cooler air, while still remaining relatively protected

AEM Induction Systems designs air intake systems in many different configurations, however AEM is best known for its pioneering in the development of cold air intake systems. AEM cold air intake systems trace their roots back to 1994 when AEM began selling its first packaged cold air intake system for the Honda Civic CRX. Increasing horsepower and torque on early fuel injected vehicles was easier than it is today. However, even then AEM understood the benefits of providing cool dense air from outside the engine bay in the quest to improve power safely and efficiently. AEM engineers seek to bring cooler air into the engine because cooler air has greater mass. Paying attention to air inlet temperature management during AEM cold air intake development helps to bring in air with greater mass which encourages consistent and reliable horsepower and torque gains.

Ideally AEM will design a cold air intake, CAI for short, to relocate the air filter outside of the engine compartment. The traditional cold air intake positions the air filter inside of a wheel well, behind a headlight, or in front of the radiator to provide cooler air, while still remaining relatively protected. However, modern cars and trucks are becoming increasingly 2 in an effort to squeeze power, fuel efficiency, and low emissions from every drop of gasoline or diesel fuel. This has required AEM engineers to continually stay at the forefront of AEM CAI development and has resulted in some rather creative cold air intake designs.

AEM believes that even though a long air intake tube leading to the front wheel well may not be suitable for every vehicle, maintaining inlet air temperature (IAT) at or near ambient air temperature is crucial. This has led to AEM Induction Systems utilizing alternative CAI designs such as enclosed air box designs, additional fresh air sources, or even a hood scoop in the quest for making usable horsepower, safely, and consistently. The engine control unit (ECU) in modern cars will retard the ignition timing as air temperature increases causing the engine to run more conservatively and in turn, making less power. This makes airflow, air temperature, and air quality coming into the engine important for maintaining peak performance.

AEM engineers design AEM cold air intakes as a fully integrated component of the vehicle. Because increasing airflow and reducing restriction is only part of the power equation, significant testing is performed to assure proper air inlet temperature management. AEM cold air intake owners can feel confident knowing that their AEM CAI is designed to improve performance safely and in a usable RPM range. AEM cold air intake systems are backed with a lifetime limited warranty giving further assurance that AEM is confident in its products.
