Sorry. I couldn't understand your question, but it looks like you are having problem finding a correct one for your car. Best bet is remove your old one, bring it to the store and match it up. You might want to use o2 sensor wrench. It's much easier with it, and don't forget to spray some PB Blaster. I've heard that you don't have to splice wires these days because aftermarket plug and play o2 sensor(Bosch?) is available for 240 now. I bought mine from dealership though, and it's easy to replace. Do you want to seafoam your car before replacing o2 sensor? You can search about it if you want.

Should only be 2 sizes of O2 sensors, 240s (and almost all Nissans I believe) use the larger ones.

Any autoparts store should be able to get one. They must be pretty dumb to give you the wrong one if you told them what car it was for. Just go back and ask for the other one.

Any auto parts store should have Bosch o2 senors.

i found out the problem.

it was an adapter connected to the o2 sensor making the part you screw in bigger
