AEM X-Series Wideband UEGO AFR Gauge Kit

AEM X-Series Wideband UEGO AFR Gauge Kit (30-0300)

Transform Your Engine Tuning with Precision AFR Monitoring

The AEM X-Series Wideband UEGO AFR Gauge Kit represents the pinnacle of air/fuel ratio monitoring technology, built upon unique, patented X-Digital technology (Patent 9,575,030). This cutting-edge gauge delivers the fastest responding wideband air/fuel ratio controller performance proven in independent testing against 17 competitor products.

Key Features and Benefits

Superior Display Technology

The gauge features a 2 1/16th-inch (52mm) diameter mounting surface with a modern center display that is 87% larger than previous AEM models. This enhanced visibility ensures critical AFR data is easily readable at a glance, even in challenging racing conditions.

Universal Compatibility

Compatible with EFI or carburetted applications, the gauge works with multiple fuel types including gasoline, methanol, ethanol, diesel, propane, and CNG. This versatility makes it ideal for virtually any performance application.

Advanced Sensor Technology

AEM co-developed its new wideband sensor with global automotive supplier FAE, resulting in a design with faster response time and improved reliability in high-performance vehicles. The kit includes the high-quality FAE sensor for optimal performance.

Streamlined Installation

With an ultra-slim depth of less than one inch overall and a cup depth of only 0.200 inches, this gauge fits in locations where traditional gauges cannot, expanding installation possibilities dramatically.
