quick question it may have already been asked sorry in advance if it has. but can i use a 2002-2006 Oxygen Sensor on my 97 or are the treads a diffrent size. i just bought the wrong one so that is why i am asking thank you in advance. oh yeah one more thing it is past the cat and its the 4wire o2 sensor

well i hooked it up anyways. it seemed to work fine. i am not running rich anymore and no codes are popping up except for p500 so it seems to work!
