2-1/16" A/F WB | For AEM | Classic Design

The Air/Fuel Wideband Gauge keeps you informed on your engine’s air/fuel mixture using data from external wideband controllers. Designed for seamless integration with aftermarket systems, it gives you a clear view of AFR during idle, cruising, and acceleration so you can dial in tuning and monitor performance with confidence. Built to reflect real-time changes in combustion, it helps you catch lean or rich conditions early. A precision stepper motor keeps the needle smooth and steady—no bounce, no guesswork. Built with a durable housing and solid aluminum bezel, it’s made for demanding driving conditions and long-term use. Made in the USA and backed for life.
