I'm running 8.8mms on the windsor and its fine. Set of top guns should only cost you about $60.

I am running 9mm Spiral Core leads on the LPG ute.
Also got myself the Denso Iridiums as well (cheaper than NGK) ... got them from Toyota as they are cheaper than Ford.

what are the densos worth? NGK Iridiums go for about $18 each.

Depending on dealership ... anywhere between $6-$10 each for the Iridiums.

6, 7, 8, 9 and 10mm are all the same performance wise, the thicker the cable only means more insulation around the conductive core, its what the core is made out of that makes the differance.
Bursons have the Irridiums for the V8's for $11 trade.

I replaced my original platnum plugs @ 93,000 ks with NGK iridums & it made a HUGE difference.... car felt alot more responsive, prob a bit that the old plugs we're worn out with doesn't help... i paid less as i work for Burson, still a good price for trade....
