2016 GRiSO...So i recently had a spark plug wire fail at the boot. (Burned a whole right through it and it was arcing to the valve cover). The part number on my plug wire is: 642221
The reference manual/exploded diagram gives me a part number of: 640912
I found one on evilbay new but that number is: 642243.. which is the same on several websites.
I can't find anything that is the same number as what i have. Any suggestions or prior experiences?

So i've been doing some research... any experience with the ngk x4k wires? I guess they were previously impossible to get in the states but found some for sale directly from Japan.
