Customer Review: (see review/s)
  • Bought 50410 for car..Car was scanned with no error codes etc...Installed failed same day within 30 miles and Eastern Doesn t care ...HORRIBLE PRODUCTS AND CUST SERVICE...DO NOT BUY FROM EASTERN OR CCFL>>>>>Here is another cust below..Eastern converter failed again with no help from compnay..No but I used a Magnaflow 46006 on mine after wasting bucks on an Eastern direct-fit replacement converter. The eastern barely got outta of the garage before the light was back on. The Magnaflow has been good for over 1k miles now.
