Up for grabs I have a Autometer ultra series Boost gauge and a Air Fuel Gauge with the sensor in perfect working condition. The sensor is NEW never used, the gauge was used but still looing new. Both items come with everything you need to hook it up.

Boost gauge for: $45

Airfuel Gauge with narrowband oxygen sensor: $140

I have pictures I can email you if ur interested. These items are being sold because I replaced them with other gauges.

Thanks for looking,

whats the difference between narrowband and wideband?

if I welded a bung in my exhaust I could monitor my air/fuel ratio with the guage?
