I need a front o2 for my d16. The car was obd2 so the rear sensor is still in the cat. It is now converted to OBD1. My question is, can I use the rear o2 for the front since its not used anymore??? I don't wanna buy one if I can just use what I already have. HELP IS APPRICIATED!!!

 

you would have to move it I belive and just plug the other hole but I dont see why not.

 

same one pal... good to go

cool...all the info I needed....I'm replacing the high flow cat with a full 3" exhaust anyways, so I won't have to plug anything. It'll definetely save me some loot! Thanks

 

how come they have different part #'s

 

I noticed that too, but the reason I asked was because I was looking for replacement ones, and alot of the replacements were the same front and rear.
