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!

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.
