Best Runner up: AEM Wideband AFR Gauge kit

Buy on Amazon

Aem has been making great kit for years, thanks to a combination of clever design and high-end materials. The X-series wideband uego afr controller gauge is the fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitor wideband afr controllers. It includes a bosch 4.9lsu wideband uego sensor. Its slim depth (less than one inch overall) and ultra slim cup depth. The sensor heats up and it can burn out if not installed correctly. This creates the perception of a larger overall gauge, but in a common 52 mm size for easy mounting. The gauge needs to operate as specified so wire in the gauge has 12v power to run, not accessory. It is allows for free-air calibration as sensor ages if user desires.
