Where is number 7 spark plug on 4.6 liter Triton engine?
There's no standard "number 7" spark plug on a 4.6L Triton engine. The 4.6L Triton V8 is a two-bank engine (two rows of cylinders) with only 8 cylinders total, numbered 1-8. Therefore, a #7 plug doesn't exist. You'd need to consult a diagram specific to your year and model of vehicle to identify the location of each of the eight spark plugs. Your owner's manual or a repair manual specific to your vehicle should show this.
