If your Mini Cooper is running rough or throwing a check engine light, the upstream O2 sensor might be the issue.

This is a Bosch 13878, a direct-fit oxygen sensor for 2002-2008 Minis with the 1.6L engine.

It's a 4-wire sensor that screws right in and plugs into the factory harness.

It replaces a ton of part numbers: 234-4457, OS6245, 11780872674, and more.

Check your compatibility, but if it fits, it'll get your Mini breathing right again.
