Haltech’s Wideband Display Gauge displays Air Fuel Ratio (AFR) down to 0.1 accuracy through a 21 colour LED sweeping needle display for immediate reference to engine AFR. An integrated three-digit digital real-time display is also a key feature in the Haltech Wideband display gauge.

The slim line design of the Haltech Wideband Display Gauge (only 3/4" or 18mm thick) allows this unit to mount well in surface mount configurations, the Haltech Wideband Display Gauge also fits neatly into standard 52mm (2-1/16") gauge pods.

This gauge is to be used with the Haltech Wideband O2 Tuning Kit, not a standalone unit.  It can be ordered with the Haltech Wideband O2 Tuning Kit here.
