The Next Generation of Cold Air Intake Technology
Once again AEM is raising engineering standards with an
all new series of innovative air intake systems. With a
revolutionary ETI module and fully integrated design, we
have eliminated the need to detune or stage an air intake tube
diameter as it crosses the MAF sensor. The sensor is
electronically adjusted to read proper air density instead
of using physical tube designs intended to "trick" the MAF
reading. The result is bigger horsepower and torque gains.
Most modern fuel injected cars use a Mass Air flow (MAF)
sensor to determine the air flow rate into the engine and
meter fuel according to input from the sensor. The relation
between the voltage output of the sensor and mass air flow
is adversely affected by a shift to a larger diameter air intake
tube because the airspeed is reduced. This causes the MAF
sensor to "under report" air flow causing a lean condition or triggering a
Check Engine Light. To accommodate MAF sensor reporting, many intake
systems reduce the diameter of the intake tube near the MAF sensor to stock or
near stock size because of the need to maintain the correct air speed for the
sensor to report the correct flow rate to the ECU.
AEM Cold Air Intake Systems are designed to boost power and performance. AEM's ETI Air Intake Systems use an alternative design approach that allows the intake tube to maintain its diameter, resulting in more air flow into the throttle body. The ETI Intake System allows AEM to tune an engine for even more power by avoiding any tube down-sizing that will reduce overall airflow and horsepower. Instead, the ETI electronically communicates with the MAF sensor to ensure an accurate amount of fuel is being delivered even though the tube is larger in size than the stock system. This means the vehicle maintains the calibration as intended by the factory while enjoying the benefits of our custom designed aftermarket air intake system.
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.
