its easy and done in about 5-7 min. First, there is a clamp that holds the mouthpiece to the turbo, need a flat blade screwdriver to undo. Then you probably have a wire that goes very near to the mouthpiece and clips into the turbo, undo from turbo and pop the plastic holder out of the hole. Then undo your intake hose from the mouthpiece and you should be able to remove it to start grinding on it.
