Which is the correct O2 sensor?

[SEgirl]

The Honda dealership says I have a bad O2 sensor (the one by the cat so I'm assuming that's the downstream one) and recommend getting an aftermarket one since theirs are so expensive. From other threads, it sounds like NGK or Denso is the preferred brand, but there are several different Denso model numbers to choose from. Would any of these work, or is there a particular one? Car is a 93 Accord SE sedan.

NGK 24169 is for the SE

Honda does not make oxygen sensors. They buy them from companies like NGK/NTK and Denso. They do this with all kinds of parts like wheel bearings and water pumps, too, but NTN and Aisin aren't the same type of household names that NGK and Denso are. In your case, the NTK 24169 is the original oxygen sensor that came on your car.

Also note, the CB7 only has one O2 sensor, either mounted at the bottom of the exhaust manifold on the F22A1 or in the down pipe ahead of the flex section that goes into the catalytic converter for the F22A6. Both are between the engine and the cat; there isn't a sensor downstream of the converter.

Thanks for the help, guys! Got the O2 sensor ordered, so that combined with a new exhaust (hopefully put in this week) will fix the current issues.
