Remember when you needed a bulky Wideband Controller box to install a stand-alone wideband air-fuel ratio gauge?  Fortunately, those days are gone!

The new Holley Analog-look Wideband O2 Gauge contains all of the O2 sensor controller components right inside the gauge.  That means no bulky box to install.  And since this is a stand-alone unit, it can be used completely independently from the Holley ECUs.  (If you are looking for a Wideband O2 Sensor gauge that will communicate directly with your Holley ECU, Look Here.)

So, what does "Analog Look" mean?  It means that you can the attractive looks of an analog sweep pointer in a gauge that is pure digital precision at heart.  No more blinding LED numbers on your dash, this gauge will look much more natural with your other analog gauges.
