alright, i got an 02 sensor directly from nissan (the slim one) and its not big enough. To my knowledge thats the one ment for the redtop (what I own) and the fat one was for S14 sr's. Could the turbo extension from a S14 be on my redtop? or did the fat ones also come with redtop s13's.
Does anyone know the nissan part number for the fat one? If I can get one fairly soon, a brand new slim one will be up for grabs soon..
