Man I was really on the rope about buying these but for the money and quality you can't beat it. I installed them and they worked great I'm happy

Unlike many of the other cheap sensors, Denso O2 sensors seem to work as well as OEM sensors.

Worked on my 2002 Pontiac Trans Am V8

Had some Bosch units that didn't last but a few hundred miles with my new long tube headers. I was getting horrible gas mileage, backfiring, fouled plugs, etc. I did some research online this is one of those parts that are finicky and most preferred Denso over Bosch. Apparently there are many people that have good or bad luck with either brand though. 4k miles later and they're still sensing though :)

I bought a pair 2 years ago for my 02 Camaro SS, they finally gave out. I bought another pair and the car runs better than ever. P.s. if you have longtube headers like me you're gonna need a harness extension which I bought on amazon and you should be good.
