GlowShift’s Tinted 7 Color Series Dual Digital Wideband Air/Fuel Ratio Gauge Kit allows you to closely monitor and fine-tune the left and right banks of your engine simultaneously from a single gauge. Experience a cutting-edge look and innovative design that features an easy to read, ultra-bright blue LED digital numeric readout on a black gauge face which displays your vehicle’s air to fuel ratio from 10.0 to 20.0 AFR. With a dual wideband air/fuel ratio gauge you can 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 because of having only one oxygen sensor installed. Wideband air to fuel ratio gauges offer multiple benefits for high performance race cars, or any vehicle with a V6, V8 or V10 engine, which include maximized horsepower and added fuel economy. This allows you to carefully map out your vehicle’s air/fuel ratios through the range of RPM and manifold pressure, resulting in maximized power output. The 0 to 5 volt digital output allows you to connect the gauge to any data logging or engine management system to log real time data for more precise tuning, and this gauge can be used on any vehicle that runs on gas. GlowShift’s Tinted 7 Color Series Dual Digital Wideband Air/Fuel Ratio Gauge Kit will add a unique look and style to the interior of your vehicle while also monitoring your exhaust system to ensure peak performance.
