All AEM Cold Air Intake Systems are guarenteed to boost performance and power. These air intake systems use a patented dual chamber that is designed to maximize 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 intake 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.
We have found that inlet length plays a vital role in the power production of Dual Chamber systems and not all Dual Chamber cold air induction systems relocate the filter outside of the engine compartment. In these cases, we performed extensive temperature testing to locate the filter in the coolest area of the engine compartment to achieve the lowest inlet temperatures possible. Please refer to our temperature testing procedures for more information.
Some cold air intake systems we sell are not legal for use in California or other states adopting California emission standards (Their CARB Exempt status is listed as "no"). These same systems are street legal in all other states. Systems that are CARB exempt are street legal in all 50 states. Please use our part number search to identify the CARB status of a part by vehicle.
