AEM Digital A/F Wideband UEGO O2 Controller Gauge
AEM's World-famous Wideband O2 Air/Fuel UEGO (Universal Exhaust Gas Oxygen, “you-way-go”) Gauge is a must for anyone looking to maximize engine power and safety. When tuning an engine, accurate air/fuel ratio data is critical. Running rich can cause a loss in power, while running too lean may result in serious engine damage. The AEM Wideband O2 Air/Fuel UEGO Gauge features large LED numerals that can quickly alert the user to even a .1 change in air/fuel ratio, providing time to shut down an engine before damage occurs. Each gauge comes with interchangeable black & silver bezels and black and white gauge faceplates for multiple color combinations.
