More than likely, your truck is equipped with the square EGR cooler 6.0, which is compatible with the Sinister Diesel Basic Solution™ Kit for 2004-2007 Ford Powerstroke 6.0L (Blue Square EGR Cooler). To verify, trucks built after 9/22/03 use the square EGR cooler, while earlier models (pre-9/22/03) have the round version. On 2004 models, you can check the 12th digit of the VIN: 'A' means a round cooler, while 'B', 'C', 'D', or 'E' indicates the square EGR cooler 6.0.
