AEM Dual Chamber Intake SystemThese air intake systems use a patented dual chamber design that maximizes horsepower and torque - typically producing even more power than our own 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 system utilizes a dual chamber (using two different diameters and lengths of piping) that creates multiple frequency sound waves to produce a large area under the curve. These sound waves help charge the cylinders with more air and are what enables them to outperform our cold air systems. AEM has found that inlet length plays a vital role in the power production of Dual Chamber systems and not all Dual Chamber 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.
