Prosport Premium Analog Wideband Gauge Kit – 52mm

You won’t find a better value in a wideband air/fuel meter than this. The Prosport wideband kit comes with a genuine Bosch wideband oxygen sensor, the gauge, cabling, and even a weld-on sensor bung. The 52mm gauge face displays air/fuel ratio in a 270-degree sweep that’s easy to read. When the gauge is powered, off, the face is completely dark. ALL Prosport wideband gauges include 0-5 volt output signal and use the latest 4.9 Bosch sensors while most of the other brands use the older 4.2 Bosch sensor. Includes gauge, wiring harnesses, oxygen sensor, weld-on bung, gauge hood, and instructions.

The Premium wideband gauge is available in amber/white or green/white LED illumination. It can be wired to display in one or the other color, or switch based on whether the car’s lamps are on or off.  (Note that Prosport’s “amber” color looks a lot like “red” to us.)
