What's a good set of spark plug wires for a 91 ultra classic

 

I usually buy the kit at auto parts and cut them myself. They work great.

 

I bought Magnacor for mine.

 

Screamin Eagle 10mm is good.

 

Any 8mm or larger if you like but not necessary. I've always used accell.

 

I went with the Thundervolt 50 10.4mm wires from Sumax, they work good and in my opinion are absolutely beautiful.

I also use their Extreme Duty battery cables and love them too.

And before someone says it, I will say it myself, these cables are way overkill but I'm just that kind of guy.

 

Any spark plug wire is good (as long as it's not copper cored) the fatness makes no difference to performance whatsoever but 10mm ones will make your ***** grow an extra inch....

 

Hmmm..... my wife got those as a present for me several years ago and just a few days ago asked me if they made wires like that for cars too

 

Those fancy yellow ones are worth 10 HP!

 

This is probably a dumb-*** question but; whats the problem with Cu ?
