AEM's Wideband that combines a gauge, a single-channel analog output, and a Bosch O2 sensor in one unit!

Now includes black and silver bezels and black and white faces! One part number, 6 color combinations!

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.
