Not worth it , to expensive for something you won't even tell the difference. But that's just me.

so, will 8mm plugs really make a difference over 7mm and so I need a special cap for 8mm wires?

8mm wires are better insulated, so less chance of cross talk between wires that run close together. (there is a tech service bulletin for plug wire routing, to solve this problem on the cheap stock wires....) Don't need a special cap to run them.

No special cap, just get one with brass inserts. As far as I'm concerned unless you have other extensive ignition mods done, 7's are more than adequate for a stock setup.

ok good, 8mm wires it is, now can I use those ones from the link from advance? If not, which ones to use and where to get them, ill be putting them on stock champion plugs

I gave him that link in a previous post here. ;)

You cant use the ones in your link, look them up again and get the right ones.

well give me a link on which 8mm I can use?

Never mind, that picture is wrong because thats not the right cap either. Don't pay for them until you confirm they have straight boots and the right cap, rotor and plugs.

which one are you talking about?
