The oxygen sensor, or O2 sensor, measures the amount of oxygen in your vehicle’s exhaust gases. Your engine’s computer uses this data to help figure out the current air/fuel ratio, which allows it to maintain fuel efficiency and emissions standards. If your ride starts running rough, you may need to clean or replace this important sensor. Fortunately, you’re at the right place to get the replacement oxygen sensor you need—Summit Racing Equipment!

Narrowband vs. Wideband

A narrowband O2 sensor only informs the computer if your engine is running rich or lean. A wideband sensor measures how rich or how lean the ratio is.

Upstream vs. Downstream

Upstream O2 sensors are positioned before the catalytic converter; downstream sensors are after it.

AutoMeter Wideband Oxygen Sensors

Designed specifically for use with AutoMeter Wideband AFR gauges, these wideband exhaust oxygen sensors are intended for replacement of an existing sensor(s) being utilized by an AutoMeter wideband air/fuel ratio gauge. The sensors are fitted with a laser-etched calibration chip which prevents the need for free-air calibration when used with the AutoMeter gauges for which they are specifically designed. Each sensor is factory-calibrated by Bosch for accuracy within 0.1 AFR.
