Replacement parts worked as expected

Mechanically on my 2010 HHR (2.2L) and it works great. Also, I saved a lot of money by buying through this company (almost 40% cheaper here).

Pros
  • Good product for the price
Cons
  • Slightly torn

OEM quality is the best in Oxygen

Amazing item. Received the sensor a day early and it was the exact part the auto parts store was asking $80 for. Bought at half price on Revain. Came with a plug and a copper anti-seize. Plug and play and OEM quality

Pros
  • An absolute legend
Cons
  • Communication with seller

This is not a direct replacement for the 2004 Buick.

This is not a direct replacement for the 2004 Buick Lesabre. The connector is different and will require splicing the old connector from the failed sensor. It also has smaller wire gauges than OEM.

Pros
  • New
Cons
  • Expensive

This Denso replacement actually appeared to be of better quality than the OEM sensor

Installed on my 2006 Chevrolet Cobalt LS at about 170,000km. The check engine light said the rear oxygen sensor was bad and I was due for the state inspection. This Denso replacement actually appeared to be higher quality than the OEM sensor. It installed well and I passed the test with no problems. After several thousand kilometers I had no problems.

Pros
  • . Fine!
Cons
  • Could have chosen a newer model

Same sensor, half the price!

Check engine light on my (100,000+ miles) 2000 Saturn SL. I went to O'Reilly Autoparts and borrowed their diagnostic tool (saved money by not taking it to the shop) and it showed the front oxygen sensor was bad. I bought the front and rear sensors as the rear one will probably fail soon. Front changed as it was easy. I asked a mechanic to replace the rear end (right after the catalytic converter) as it had a shield welded on it that was difficult to remove and I didn't have the tools. All is…

Pros
  • Consistent test results
Cons
  • Some imperfections
