AEM Digital Wideband UEGO Gauge Kit Without Sensor - High Performance Air/Fuel Ratio Monitor for Racing, Tuning & Diagnostics - Perfect for Dyno Testing, Track Days & Performance Upgrades

Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.
