Subaru Replacement O2 Sensor


Your vehicle is special because of its great performance and great style, and to have it purring along in its best shape you'll need the acme in quality parts and accessories. Buyers who select a Subaru are aware that performance and style are worth every penny; quality accessories will keep your car or truck in the best condition.

Some of our Customer Reviews
Somewhat Satisfied
Reviewer: Sam

Great, easy, informative sales transaction and shipping for my downstream O2 sensor. I should have ordered the upstream sensor at the same time. My fault--doing that now.

2005 Subaru Legacy Oxygen Sensor

Very Satisfied
Reviewer: Sam E.

The engine code relating to the upstream O2 sensor went away after the replacement sensor from PartsGeek was installed.
