Black 7 Series Dual Digital Wideband Air/Fuel Ratio Gauge

Features & Functionality

GlowShift’s Black 7 Series Dual Wideband Air/Fuel Ratio Gauge allows you to closely monitor and fine-tune the left and right banks of your exhaust system simultaneously from a single gauge. This wideband air/fuel ratio gauge features dual LED screens that display large, blue digital readings from 10.0 to 20.0 AFR. This gauge features a diameter of 2 1/16" (52mm) with a black gauge face and clear lens.

Wideband air to fuel ratio gauges offer multiple benefits for high performance race cars or any vehicle with a V6, V8 or V10 engine that include reduced emissions, higher fuel economy and maximized power and engine performance. This allows you to carefully map out your vehicle’s air/fuel ratios through the range of RPM and manifold pressure which results in maximized power output.

GlowShift’s Black 7 Series Dual Wideband Air/Fuel Ratio Gauge would be a positive addition to any vehicle, providing a unique look and style while also monitoring important engine functions.

Dual Wideband vs. Single Wideband
A dual wideband air/fuel ratio gauge allows you to quickly and accurately diagnose which side of the engine is either underperforming or causing an issue that can be adjusted to prevent engine damage. A single wideband gauge gives you those same readings and diagnosis, but you cannot pinpoint which bank is underperforming versus the other due to only one oxygen sensor being installed.
