The AEM Cold Air Induction System not only adds performance, it showcases what performance engineering can do in terms of maintaining emissions levels, too. Even though we in Canada aren’t under the California emissions regulations, it’s nonetheless notable that the unit AEM built for the ultra-low emission Honda Accord (PN 21-415) not only increased horsepower and torque, it also became the first to gain CARB exemption for a ULEV vehicle. The induction system improved performance because air mass flow to the engine is increased due to reduced inlet temperature. Lower air temperature results in increased air density, creating more horsepower at the point of ignition. All AEM cold air systems are lightweight aluminum and powder coated for superior heat insulation. According to the company, this extra process helps seal out engine compartment heat, preventing it from affecting the air inlet flow.
