Performance Amber/White 52mm - Air/Fuel Ratio Gauge

This analog air/fuel ratio gauge reads the signal from your vehicle's factory (narrowband) oxygen sensor. It's a quick visual check of whether you're running rich or lean, and is most useful for spotting a lean condition under wide-open throttle.

• Amber & Super White dual-color display: run white by day and amber at night, one color all the time, or reverse them.
• Full 270° LED sweep: a wide, easy-to-read arc powered by a precision electric movement.
• Tinted lens: the smoked face blacks out completely when the gauge is off for a clean, stealth look.
• Startup needle sweep: the pointer performs an opening ceremony every time you power up.
• Sender included: a matched precision sender ships in the box, so readings are accurate out of the gate.
• Free tech support & 1-year warranty.
• Uses your factory O2 sensor: no wideband sensor or bung to weld in.

Note: This is a narrowband AFR gauge that uses your stock O2 sensor — it is a lean/rich indicator, not a wideband tuning gauge. No separate sensor is required. Includes mounting hardware, wiring, visor and instructions.

Part of the Prosport Performance Series (Amber/White) — the standard-tier gauge in a GaugePods kit. Sized 52mm (2-1/16") to drop straight into any GaugePods pod. Made to order and matched to your build.
