Review on Upstream Downstream Replacement Oldsmobile Silverado by Joey Richardson

Revainrating 1 out of 5

Do not buy these Chinese O2 sensors

Put them in my 23 year old Buick Century on the upstream side and the machine will still perform poorly. I took it to the mechanic, I asked them to put it on the oscilloscope or the computer, some of you may know that there was no connection in the O2 sensor! The whole reason I bought it was to do it for myself and not take it to the shop, so I had to get a Bosch O2 sensor a few hundred bucks later to solve the first problem. Do not buy them made in China as it says on the O2 sensors packaging.

Pros
  • Spare parts
Cons
  • Some defects
