Let's talk O2 sensors
 

I'm getting fault code P0153/P1276 again after replacing my O2 sensors two months ago with salvaged used ones. So time to bite the bullet and buy new. Pelican has Bosch direct fit for 111.00 each and I believe free shipping. I've bought a ton of parts from Pelican over the years never a complaint. But I plan on replacing both front sensors so that's 222.00. Did a search on this site and others and the Bosch 15182 is also a direct fit. Everything I find on the net states the 15182 is the OEM sensor. Looked on Amazon and they sell the 15182 from two different vendors, one is 72.43 ea. and free shipping the other is 62.00 ea. and 10.00 shipping for two so 144.86 free ship or 134.00 with paying shipping. Either way saves quite a few coins is there any reason not to use the 15182 ? The pictures on the net look exactly like what is in the car now down to the blue protective cover over the wires. So is there any reason not to buy the 15182 ? I also see Denso brand for similar price. Car is running great so I'm not in a panic but would like to order in the next few days. Local FLAPS seem to all be around 125.00 or more. Advice please :D If it matters the car is 02 S and I'm replacing the upstream sensors.

I had to replace an o2 sensor, post cat, which I think was 15183, I got it from amazon and it worked like a champ. I got the part number off Mike Focke's website.

Steve you are correct pre-cat are 15182 and post cat are 15183. In my search Mike Focke's website came up that is some of the info I went on. Glad it's working out for you.
