Was looking at some NGK spark plug wires. And I seen there was 8mm and 10mm wires.
Ive heard the 10mm is more for turbo'd cars and 8mm is for daily is this true or does it really matter?

And which sparks plugs should I run in my b18c?

8mm works fine. I would stick with OE wires. Money better spent on something like a velocity stack.
