Keep an eye on your engine's mixture with this Dyno Racing air/fuel ratio gauge.
It's a classic 2-inch (52mm) analog gauge with a cool smoked lens and an LED display.

The pointer moves from LEAN to OPTIMAL to RICH, so you know exactly what's going on.

Runs on standard 12V car power (10-15V DC).
Important note: This is the gauge kit without the O2 sensor, so you'll need to grab one separately if you don't have it.
