My Nizzy cooler is the 'big' cooler. got it second hand off a forum member, it was part of their stage 2 kit. It came with the pipe that goes under the headlight. I ordered the rest of the pipework to the TB from plazmaman for around $200. I also have the battery relocation and intake from the stage 2 kit, so it all works/fits right. I would love a plenum to finish it off, but a second hand one on its own is fairly rare... How it looks now
