I have a 93 SI. with a jdm 97-01 swap in it. I need to replace my o2 sensor but do i get one for 97-01 right? the wires are 2 black, a green, and a white. The factory one for my car is about $240, and the universal is only $70 so im thinkin bout gettin that universal. anyone know what wires are which on my car? cause i have to cut them myself and wire it together. thanks

 

Get the 02 sensor that matches your ECU....

obd1- get an obd1 02 sensor
obd2- get and obd2 02 sensor

I just bought my secondary 02 for my 96 Si from http://www.sparkplugs.com and I paid like $80 for an NGK one...works like a champ too
