I have an 03 gt, and just recently we put the O/R H on but we put the O2 mils in the front. was that the right place for my year, or do the mils need to be in the back O2 sensors .?? Thanks
You should have 2 to connect for the front(connects to the top of the pipe, near headers) and two in the middle. The two in the middle is where you need the MIL eliminators. For an 03, I'm not sure if you need the extensions though for the front.
Edit: You need them in the middle. I thought you were talking about the actual o2 sensors.
