I checked Courtesy Parts website and the O2 sensors are same for 200-2003 engines. But when I looked at BOsch's part numbers, they have different part numbers but the sensors look the same. Even the prices are around the same range. Are the Bosch sensors the same even though the part numbers are different?

P.s. I'm asking this because I can get the 2000 sensors for way cheaper than the 2002 and my car is a 2002. I just want to make sure they are the same before I go ahead and replace them. Any help is appreciated. Thanks!

 

Federal 00-01 had 2-O2 sensors no pre-cats and the 02-03 had 4-O2 sensors total, (2) 3-wire primaries and (2) 4-wire secondaries. Correct me if I'm wrong please...

 

Fuel management & emissions components change about every two years.

I would get the correct sensor for my application, unless you like to experiment.
