AEM’s Wideband that combines a gauge, a single-channel analog output, and a Bosch O2 sensor in one unit!
This unit has both an LED readout and a sweeping LED series that changes colors as the air-to-fuel ratio progresses from rich to lean. The 52mm (2-1/16”) sizing works with most gauge pods and makes for a simple, clean installation.
No laptop or EMS required for monitoring. Also includes a 0-5 volt signal wire that can be used with most aftermarket standalone or datalogging systems for additional A/F ratio output monitoring
Is the "6-in-1" design meaning you can change the gauge face color and gauge bezel color between white, silver, and black to make up 6 different possible combinations for matching existing gauges in your car!
