Your cart is empty.Delphi oxygen sensors feed data to the ECM which helps the engine to run as efficiently as possible while maintaining fuel mileage and reducing emissions. Because the amount of oxygen the engine pulls in can vary due to altitude, air temperature, engine load, the oxygen sensors optimize combustion by monitoring oxygen levels, so that the proper amount of fuel can be combined with the air.

What can you say about an oxygen sensor that works?It has anti-seize on the threads.This particular version may be longer than an O2 socket, you may need a crowfoot or wrench.Code is gone.These last about a year or 12 thousand miles; sometimes longer.

Got the sensor in the mail but didn’t put it in for a couple weeks. As soon as I put it in, I was getting an intermittent check engine light that lasted a few days before becoming a constant problem. Unfortunately I discovered the bad sensor just past the 30 day return window. So not only did I get a low quality sensor but I am stuck with it since it has a short return window. Would have been better off with a parts store generic sensor

Fit perfectly and seems to be high quality. Check engine light has been out for a month now. Great value!

Works as intended. Replaced an old one that got lazy and was causing engine to run rich, verified with scan tool, also noticably less fuel odor at idle. 1992 Chevy C1500 with 305.

Replacement took 15 minutes, start to finish, even fussing with wire harness loom to hook in new connector. Instant start up and a couple of loop cycles and engine runs noticeably smoother. Well spent money and time.

This Delphi O2 sensor was an exact OEM match to my 1995 GMC C2500 Extended cab Pickup. Carefully packaged for a clean and delicate installation. (don't touch the internal probe when installing.) I am really glad to have found this Delhi product on Amazon at a very good price too. (don't clean, replace,-this is also electrical and who knows what you cannot see inside, is all about)If your vehicle is GM go Delphi. I believe it is OEM or a GM replacement. ITS ALL GOOD!
