Was it bosh or champion the dakotas didn’t do well with lol. I remember reading somewhere that dakotas done like one or the other

 

These trucks don't like rare-earth plugs. They do fine with just about anyone's copper plugs. They don't like bosch O2 sensors though.

 

Well it may be the 2.5 my 2.5 likes either Bosch platinum or Iridium fine point tried both no problems. When I rebuilt it 2 years back I used the Bosch platinum but wanted the Iridium again that's what I used before the rebuild. My Bosch Iridium are ready just haven't done the swap out yet a little bit of a pain replacing one plug behind the A/C compressor.

 

The four popper may be more forgiving.

 

i curently have e3's in mine (some one else bought for me) and it seems to like them.. went from 11 mph to 16 mph after they were installed (most that mph increase probably came from all the other tune up parts and replacing the stuck callipers lol) i do have a bran new set of champions to install 1 day
