1994 E150 GLERA

I want to replace my sparkplugs wires. I ordered a kit from my marine dealer an its a make your own kit.

Which i'm fine with... My question is the wire.... The pre-cut pieces say "hypalon ignition wire - copper conductor" on them...

Should i use these??

Or do i need "Evinrude, Johnson 931-4921 Spark Plug Wire Set - CDI Electronics"

the special grey wire set made by cdi??
