Included is AEM's wide band oxygen sensor and everything needed for a quick and easy permanent uego wideband install. Air fuel readings are very consistent and this AEM digital wideband gauge has a reputation for accuracy. A wide band UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. This AEM UEGO 30-4110 does that, and does it extremely well. If you're looking at this Digital AEM Wideband Gauge you have probably modified your car and need to keep an eye on your air-fuel ratios.
