Looking for a set of wires, and the Kingsborne wires seem to be of choice here. I'm a little puzzled though, there's only one model listed in their catalog, which is the 12-7000. On the Kingsborne site they are $29.75 for the 8mm wires, but on Outmotoring they are $69.95. Both are 8mm. The only difference I can see is the Fireguard on the set Outmotoring sells. I'm not sure if the Fireguard comes on the ones directly from Kingsbourne. Can anyone please offer some input?
