i'm no expert but basically its this simple

the better the ignition ,,, the more spark u get ,,,, the more spark have the more fuel u burn ...the more fuel u burn the better it combusts....better combustion the better she goes

11mm sounds like overkill. A good set of 8 or 8.8mm leads should do fine in a road car. You're after a consistant spark, and stock leads tend to lose the ability to provide that over time. Same with park plugs, a good set of plugs for an XR6 are fine. Going with huge, expensive leads and expensive plugs is only going to burn extra money, not extra fuel.

You won't get any horsepower increase, but you may be able to help minimise horsepower loss over time.

I have heard lot of ppl have had problems with the ignition, in regards to the EF. Myself included.

Apart from a dealer fitting the wrong plugs, I have changed these plugs to both NGK R (EF XR6 spec), and Spitfire plugs (EF-XR6 spec) !
I noticed absolutely NO DIFFERENCE between the 2, and considering that the splitfires cost me $14.00 each, and the NGK cost roughly $3.50 each, I will be continuing to buy the NGK R for now on.

I also fitted Magnacore 8mm leads, when the car was stuttering above 50Km, when it was floored. (the car wasn't pinging, the fuel just wasnt getting burnt).
I had original leads, and the wrong plugs at the time, and simply replacing the leads with the magnacores fixed this problem up immediately. (It was only when I was changing the leads, that I checked the plugs, and realised that they were incorrect, hence the purchase of the Splitfires.)

Mmmmmm. guess this story doesnt have a moral, or anything, just my experience with leads and plugs !

I picked up some top gun 10mm leads from the Summernats for a discounted price on the last day, I wanted 8.8, but they had run out...I thought the 10mm were overkill at first, so I rang teh guys at teh head office, they advised me that their 10mm racing leads were infact similar internally, but with more sheilding to prevent "crossfiring" and loss of efficiency..

they look nice and meaty installed! the same time I replaced my standard ngk plugs with teh xr6 spec plugs (slightly longer reach, and run hotter).
I did notice a little improvement over the original gear...but this is probably just restoring the strength of the spark to as new, or slightly better
