One range colder would be ZFR7F-11. the higher number in NGK plugs equal colder plugs. Standard for the 2003's 6F. One range colder equals 7F. I just did a plug change on my 2003 3.9 about 3000 miles ago and I used the standard 6F and I have had no problems.

Myself, if no ping problem stick with stock recomended plug. The amount of spark is identical. but the factury plug runs the cleanest under all conditions. The iner electroid extendes farther so gets warmer and thus the cleaning. One number is to close to really call. It will run as clean or very close. check the color of the plugs you got now. If there dark tan to near white your in the right area.My opinion
So many problems .... So little time
