July 10, 20169 yr I'm gettng a P0420 and thought the replace the upstreak O2 sensor which is about 5 years old. Advance is offering a rebate on NGK sensors so I thought I'd query peoples thoughts and experiences before buying. I'm inclined to go OE but it's always good to save a buck.

What brand did you use 5 years ago? I don't have any suggestion for you but was curious why a 5-yr-old sensor needs replacement. I still run both factory O2 sensors on my 96 2.5 with 150K miles. No CEL.
July 10, 20169 yr Author What brand did you use 5 years ago? I don't have any suggestion for you but was curious why a 5-yr-old sensor needs replacement. I still run both factory O2 sensors on my 96 2.5 with 150K miles. No CEL. Bosch premium. Worked great until about 10 days ago when I noticed the car running odd and then the CEL P0420 came up. I just replaced the gas tank due to the old one leaking and maybe I knocked/damaged one of the O2 sensors while doing it. It's also possible the cats are going. I have over 260,000 miles on this beast and there are a TON of welds on the exhaust pipe.
July 10, 20169 yr NGK is either OEM or definitely acceptable. (This is coming from someone who always advocates Genuine parts for the O2 sensors.) Emily
July 11, 20169 yr If it were a turbocharged car I would say only use an OEM sensor, but in your case, the NGK will probably be fine.
July 13, 20169 yr Author I had three spots on the exhaust welded early today which only cost $40. Here's to hoping that solves the P0420 code.
