AEM Two 52mm Gauge Set (A/F Ratio + Boost Gauge)

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. Air fuel readings are very consistent and this AEM digital wideband gauge has a reputation for accuracy.

The Boost display gauge combines unsurpassed accuracy, speed, and control with an easy-to-read digital LED interface that displays boost in 1 PSI increments, and a sweeping LED "needle" that lines the edge and moves as boost from -30 to up to 35 PSI.

Each gauge includes 24 color-coded (Red, Green, Yellow) LED lights that change from green to yellow to red for immediate reference to the measured parameter and an integrated three-digit display that reveals real-time operating conditions.
