Review on Premium Oxygen 2001 2002 Upstream Downstream by Chase Dunn

Revainrating 1 out of 5

Just buy genuine Bosch sensors

I bought these to save a few bucks on the purchase of genuine Bosch sensors for my 2004 BMW x3. However, the upstream sensors only lasted a week before failing. Also, the pin plug doesn't fit properly and you really have to plug it in. I installed Bosch sensors and everything was fine. Don't waste your time with it, at least not for BMW.

Pros
  • Vehicle Fitment-2
Cons
  • small things
