WHAT IT DOES
AEM’s Wideband O2 Air/Fuel UEGO Gauge unites unsurpassed accuracy, speed and control with an easy to read, digital interface. AEM digital gauges also offer a 0-5v analog output for use with data loggers and virtually any engine management system, such as the AEM EMS or FIC. 

WHY YOU WANT ONE
The AEM Wideband O2 UEGO Gauge is a must for anyone that has started looking for more power from their engine.  Air/Fuel ratio is one of the most important things to know when tuning your engine. Running rich can cause you to lose power, running too lean can result in serious engine damage. Large LED numerals make it easy to see when there's even a .1 change in ratio, giving you time to shut things down before damage occurs.  A Bosch 4.2LSU sensor gives the gauge its accuracy, and is the same base sensor used in many OEM applications today. Each gauge comes with interchangeable black & silver bezels and black and white gauge faceplates for multiple color combinations.
