THIS IS A VERY WELL KNOW IMS FAILURE ISSUE WITH PORSCHE BOXSTER WHICH CERTAINLY CALLS FOR A RECALL FROM PORSCHE. MY 2005 ENGINE WILL NEED TO BE REPLACED FOR 20K JUST BECAUSE OF THE VERY OBVIOUS DESIGN FLAW PORSCHE HAS IN ITS M96 ENGINES. I AM PRETTY SURE THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THIS IN PAST BUT NOBODY HAS EVER HEEDED TO IT. I SINCERELY RECOMMEND SOME ONE TO PLEASE LOOK INTO AND ASK PORSCHE TO ACCEPT AND RECALL M96 ENGINES FAILING DUE TO IMS. ANY CAR EXPERT OR MECHANIC OR DEALERSHIP CAN VOUCH FOR THE DESIGN FLAW PORSCHE HAS. ITS POTENTIALLY FATAL TOO. I SINCERELY REQUEST SOMEONE TO LOOK INTO THIS COMPLAINT WITH UTTERMOST SINCERITY. *TR
