West Central IL
I'm going to change spark plugs in a friends 99 Jeep Grand Cherokee with the 4.0 inline 6 next week.The other day I was looking at it and all I saw was a rail of some kind over the plugs and I didn't see any wires,is it all built into this rail?Can anyone give me some tips before I start this project.
