AEM's new Electronically Tuned Intake (ETI) Systems are raising air
intake engineering standards once again. The Scion tC uses 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 intake tube as the airspeed is reduced. This
causes the MAF sensor to 'under report' air flow causing a lean
condition at worst and a CEL at best. With a revolutionary ETI module
and fully integrated design, AEM's air intake system adjusts the sensor
electronically 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 out of an already very efficient engine: 9
HP @ 6400 RPM according to AEM! NOTE: Picture above shows the 08-10 model intake.
NOTE: This kit is street legal in all 50 US states.
