When it comes to maximizing your vehicle’s performance, few upgrades are as important as monitoring your air-to-fuel ratio. A GlowShift 2-1/16” (52mm) Wideband Air Fuel Gauge delivers the accuracy you need to safely push your engine to its limits.

Anytime you’re tuning for power, fuel efficiency or long-term engine health, these AFR Gauge Kits will deliver the readings needed with pinpoint precision for modified vehicles running on gas or Ethanol 85.

One of the biggest benefits of installing our Wideband Air to Fuel Ratio Gauge is real-time insight into your engine’s combustion process. By monitoring, you’ll know immediately if your engine is running rich or lean, helping to make adjustments that improve performance and prevent costly damage.

Running lean can lead to overheating, while running rich can waste fuel and reduce efficiency. By installing one of our fuel mixture gauges, we’ll help you avoid both extremes. Take gasoline AFR readings from 10.01 to 20.00 AFR, E85 readings from 6.660 to 13.31 AFR, or LAMBDA readings from 0.683 to 1.365 depending on the specific gauge version you select.

For enthusiasts adding performance modifications like turbochargers, superchargers, or aftermarket exhaust systems, a wideband air and fuel ratio gauge is a must-have tool. It ensures your tuning is spot-on, protecting your investment while giving you the ability to fine-tune for maximum horsepower.

On top of delivering accurate readouts, these AFR meters will look incredible inside of your car or truck. Select a GlowShift Gauge Series to get the right look for your specific make and model.

Beyond performance, installing a Wideband AFR Fuel Gauge adds peace of mind. You’ll drive knowing your current AFR and that your engine is operating safely, efficiently and exactly the way you’ve tuned it.

If you’re hitting the track, cruising on the street, or simply tuning up your ride, we give you the tools to stay ahead. Upgrade your ride with a GlowShift Wideband Air Fuel Mixture Gauge Kit and experience the benefits of precision monitoring every time you drive.
