What is the easiest way to change the rear two spark plugs (#6 & #8) on the passenger side of the LS1?
The easiest way to do this on a 1998 F-body is to remove the rear 2 coils that are attached to the valve cover on the passenger side. These are held on by 2 10mm bolts and take about a minute to remove. On 1999+ cars, each side has all 4 coils connected to one bracket. Simply remove this bracket, and all 4 coils will come up at the same time.
