AEM's analog E85 wideband air/fuel gauges unite unsurpassed accuracy, speed and control with an easy to read, analog interface. The AEM wideband 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. The gauges feature a Bosch sensor with an accuracy of .1 AFR, making it among the fastest and most accurate widebands available. The backlighting is user adjustable to 7 colors, (white, blue, green, red, orange, light blue, and aqua), allowing users to easily match the wideband gauge to most factory gauge clusters, and both the white and black faceplates come with the gauge and are easily interchangeable. Black and silver bezels are also included to customize the look of the gauge.
