I am getting a Mac o/r x and I know I need MIL elimanators but do I also need O2 extensions? I have heard with the 04 GT you need the extensions. Any advice?

Since your getting rid of your O2 sensors, why do you need to even hook them back up, let alone extend the wires?

when I did headers and a mid pipe I needed the extensions on my 04 gt. (I think I needed 4 but you can do with 2.)

From what I have been told MIL eliminators don't eliminate the O2 sensors it plugs in to them. Also the o2 sensors on the 04 were relocated. Understand the question before you reply.

From what I understand the 04 is the only car you do need the o2 extensions, so Im pretty sure you do need them for your car.

i have o/r h-pipe and the mils extended the reach of the o2 sensors. i dont THINK you will need extensions. mine is a 2000 i will talk to my buddy with an 04 and get back with you.

i have an 04 and had to buy 2 sets of extensions. one for the front 12', and the 24' for the rear + mil's. i dont know if this is because my h-pipe is out of a much earlier year. i think it is, i bought it used but if your rear o2 sensor holes are by the back of the trans then you will need 2 sets of extensions. 1-12' pair and 1-24' pair
