GlowShift’s Tinted 7 Series Digital Wideband Air/Fuel Ratio Gauge is essential when tuning any performance vehicle. This digital wideband gauge allows you to closely monitor and tune your car or truck’s air to fuel ratio from 10.0 to 20.0 AFR on a bright blue LED display. With this gauge you’ll have the ability to carefully map out your vehicle’s AFR through the range of engine RPM. Benefits include maximized power and engine performance, higher fuel economy and reduced emissions.

The Tinted 7 Series
GlowShift’s Tinted 7 Digital Gauge Series comes standard with a cutting-edge design that includes a black gauge face and low profile magnified tinted lens. Whether your gauge is on or off, it will look amazing courtesy of this tinted lens feature which is at the heart of the series and gives your gauge a unique, stealth-like appearance. This gauge only features a blue digital readout, but the trim ring matches the Tinted 7 Color Gauge Series, assuring that all of your gauges are a perfect match.

Digital Wideband Benefits
With GlowShift’s digital wideband air fuel gauge you’ll experience swift and responsive readings on your car or truck’s air to fuel quality values. These readings are not only provided almost instantaneously, but they’re also delivered with incredible accuracy down to one decimal point. These accurate readouts are one of the many benefits of the digital wideband gauge. The eye-catching digital display will also look great inside of your car or truck, enhancing the interior of your vehicle.

Tri-Color LED Ring
Among the features of this digital wideband gauge is a three color LED ring that indicates rich, lean and optimal values with the corresponding colors green, red and yellow respectively. Each color is displayed at the top of the gauge above the blue AFR readout, depending on which value range is currently being utilized. Features such as this Tri-Color LED Ring were included in the design with the goal of giving you the best wideband gauge possible.

Rich: 10 ~ 12.9 AFR | Optimal: 13 ~ 17.9 AFR | Lean: 18 ~ 20 AFR

    Excellent little AFR gauge! Install was super easy and the fast and accurate feedback I get from it allowed me to tune my carburetor to exactly what it needed to be. Truck runs great now!

  • Great O2 sensor

    I was able to wire this up add the bum and it works so well. I was able to see right a way that the car is lean at idle. After making some change to the idle circuit it adles so much better.
