I have always just used AC Delco wires, or a Parts store wire.
Just with Hot-Airs if you run a bare wire over on the passenger side you need to be VERY careful! I always wrap my wires in some high heat loom so they dont get burnt by the up or down pipes.....It sucks when your chasing a cly mis and it turns out that you were the cause of it!
Accel 8.8 are great. Mine almost aleways touch the downpipe, and they have never melted. There heat resistant to a certain temperature, but i'm not sure what exactly. I would go with those if I were you.
