52mm air/fuel ratio gauge for monitoring the engine's fuel mixture in real time, which is the fastest way to catch a dangerously lean condition (a common cause of detonation and engine damage) while tuning or driving hard. Black-body gauge with 7 selectable backlight colours (red, blue, yellow, cyan, green, purple, white), runs on DC 10-15V. The set includes the gauge, an O2 sensor for ratio detection, and a multi-element mounting cup that adapts to dash, pillar or pod mounts without cutting the surface.

Fitment: universal / custom - fits any vehicle with a standard 52mm gauge pod or mount and an available bung for the O2 sensor.
