Ford Focus ST250 "NAKED" DAIS Induction Kit. Due to popular demand we have developed a "Naked DAIS" (direct air induction system) for the Focus RS MK3 and Focus ST250, you can now enjoy the benefits of our high flow spun aluminium trumpet and K&N conical filter at much reduced cost over the fully enclosed "CAIS" (cold air induction system) GGF7002/3.
