Air/Fuel Wideband Gauge keeps you informed on your engine’s air/fuel mixture using data from external wideband controllers. A built-in warning light provides immediate visual alerts when AFR moves outside your set range, helping you react before lean or rich conditions impact performance. 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 with confidence. 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.
