I'm looking to replace both front and back O2 Sensors in my car so I can get rid of some CELs.

No exhaust leak BTW.

Anyway, what are your thoughts on buying...

Denso/Oxygen Sensor (234-5007) | 2009 Chevrolet Cobalt 4 Cylinders X 2.0L SFI Turbo DOHC | AutoZone.com

and

Denso/Oxygen Sensor (234-4245) | 2009 Chevrolet Cobalt 4 Cylinders X 2.0L SFI Turbo DOHC | AutoZone.com

...rather than getting OEM. Or any other non-OEM sensor for that matter.

Waste of money?

I am in the same boat, I need a new 02 sensor after going catless. I talked to CCSS3 who will be tuning me here soon, and he said to get one from the dealer, my friend works at Advance and that's the exact one they sell and he told me to go to the dealer, safer bet and close in price.

Should have both position 1 and 2. Usually your local dealer will have a close price or will match price if not depending on how friendly they are.

Rockauto.com has OEM AC Delco sensors for $55 I believe. Pretty good price and you'll know you're getting quality parts.

I work in the service dept at a dealership, and from my experience only go with oem. Denso or any other make just don't work well

I would get the OEM part numbers and google search to find the cheapest price for it. Me, personally, I ran three advance auto parts sensors in my old redline and after a week they all crapped out. The car lost power and CEL's came back. I finally ponied up for an OEM one and it was good to go. Ran it for another 35k with no problem. I would go with OEM. Just my .02
