1989 560SEL

Mercedes wraps the 4 plug wires in a bundle between the distributor cap and the top of the valve cover. Won't this increase the chance of cross firing? Especially on adjacent cylinders that fire in order like 1&2.

I've worked on '60s Fords and the shop manual was always very specific about plug wire routing to avoid cross firing. There were specific instructions on how to layout the cables on top of the distributor cap to keep them perpendicular to each other as well as instructions to keep the cables seperated from each other.

Why is it the MB doesn't seem to be concerned about cross-firing? At least not on the 560 engine.
