Upstream O2 Oxygen Sensor For Land Rover LR4 (2010-2013) & Range Rover – 5.0L V8 Naturally Aspirated, OS6129

Got a check engine light related to your oxygen sensor on your Land Rover?

This is an upstream O2 sensor for the 2010 to 2013 Land Rover LR4, Range Rover, and Range Rover Sport.

Important: this is for the 5.0L V8 engine that is naturally aspirated only.

It will NOT fit the supercharged version.

The sensor is unbranded but is a direct replacement.

It crosses to part numbers OS6129, 350-64077, 250-54072, and 18121.

It's located upstream, so before the catalytic converter.

It comes with a 1-year warranty.

If your fuel trims are off or you're failing emissions, this might be the fix.

Direct fit, just unscrew the old one and screw this one in.

Make sure you've got the non-supercharged engine, and you're good to go.
