i dont think it will the front and rear anti roll bars are to big on the facelifted models and the overall length of the new cars is lslighty longer(NOT MUCH THOUGH JUST A FEW MM) than the orginal k12.
Best bet would be to find a old front bumper and try and see if it fits. if it does then the impul one will if it. if it doenst then the impul one wont.
