NHTSA Complaint #10114310 — 1997 FORD EXPLORER

FEW MONTHS AGO I HAVE PURCHASED A SET OF BOSCH SPARK PLUGS (PLATINUM 2 PART # 4305). ABOUT 3 WEEKS AFTER I INSTALLED THEM WILE DRIVEN ON THE EXPRESSWAY ONE OF THEM EXPLODED RUINING THE WIRE AND CAUSING TO FLIP FLOP ALL OVER SPARKING LUCKY I STOP RIGHT AWAY. THE CERAMIC PORTION OF THE SPARK HAS COME OUT OF IT CLEAN CAN NOT EVEN FIND A TRACE OF CERAMIC ON THE PLUG BUT UNFORTUNATELY THE ELECTRODE OR PORTION OF IT FELL IN TO THE CYLINDER ,CAUSING AN IRREPARABLE DAMAGE TO THE ENGINE, I HAVE REPORTED THE DAMAGE AND DETAILS TO THE MANUFACTURER AND EVEN SEND THEM THE PLUG FOR INSPECTION AND EXPLAIN EVERY THING, BUT THEY HAVE RETURN THE PLUG AND A LETTER SATING THAT THE REASON THE PLUG EXPLODED WAS BECAUSE IMPROPER TORQUE. I HAVE BEEN INSTALLING THE PLUGS ON MY VEHICLES FOR THE LAST 20 YEARS AND I HAVE NEVER HAD A PROBLEM LIKE THIS AND PEOPLE I TALKED TO SAID THE PLUG SHOULD NOT EXPLODE FOR THAT REASON. I THAT IS THE CASE I FEEL THIS IS A SAFETY ISSUE ON THIS PARTICULAR PLUGS AND THERE IS NOTHING ON THE PACKAGE INDICATING TO THE CONSUMER OF THIS DANGER. *AK
