Yeah it’s not easy, you have to just use the oxygen sensor removal tool, it makes it 1000000x easier to take them off. You also need to unclip the o2 sensors completely so they are free; that way you can screw them into the defouler once you install that into the downpipes. If it’s plugged in still it will get twisted and won’t work. So unclip it completely first then use the o2 removal tool to unscrew the downstream o2 sensors
