AEM Advanced Engine Management V2 intake systems use a patented dual chamber design to produce the most power and torque of any other intake system available, even AEM's Cold Air systems. On a dyno graph, the area under the power band (or power curve) represents the amount of effort that an engine is producing. The larger the overall area under the curve, the more power your engine is making. The AEM V2 air intake for imports utilizes a dual chamber (using two different diameters and lengths of piping) that creates multiple frequency sound waves to produce the largest area under the curve of any intake system on the market. These sound waves help charge the cylinders with more air throughout the entire rpm range and are what enables the AEM V2 air intake to outperform even the AEM Cold Air systems. Testing has found that inlet length plays a vital role in the power production of AEM V2 air intake systems and not all AEM V2 induction systems relocate the filter outside of the engine compartment. In these cases, AEM performed extensive temperature testing to locate the filter in the coolest area of the engine compartment to achieve the lowest inlet temperatures possible.
