Nuther Q?: should I leave all the spark plug wires the same length?
or can they be cut to make a better looking wire loom? - they are 8MM.
any decent preformed set of plug wires has at least 4 different lengths among the 8 wires, if not having all 8 of them their own length.
you make a plug wire long enough to reach #8 and you're going to have to waste all kinds of wire coiling up the slack when you wire #1. you're also likely to have issues with capacitive crossfire such as kcombs is describing.
I wouldn't run the spark plug wires along side each other for much distance
that's what the wire looms are for. to maintain a minimal air gap between the wires and reduce the capacitive coupling.
