I think I read someone here saying that the 4.6 rear o2's were pretty cheap and had the same plugs just a longer harness, can anyone confirm? Any other sources for cheap o2's?
according to that website the rear 4.sux and the 5.0 sensors are the same. i will check out autozone to make sure, but the rear 4.6 are about 41 while the 5.0 are about 70
