Plug Wires

My '96 GT has the original blue spark plug wires on it that say "1996" on them... The car has 73k orig miles and runs fairly good and idles smooth. I'm going to change the plugs soon to some iridium/platinums, should i change the plug wires at the same time? Or are the original wires fine? How long do plug wires usually last and perform at optimum level? And if i'm changing my plugs to iridiums, etc., will i need better performance wires?

Thanks...
 
To tell you the truth, I upraded to ford racing sp wires with good sp plugs. The difference to me is that it just starts faster. It's not really necessary to upgrade them, but its cool to do it. Looks better as well.
 
Don't ever buy the Livewires. I got these for Christmas...and once they are snapped on, they are on forever. I tried to get two of them back off the same night to reposition them...and the wire ripped out of the boot. I used dielectric grease too. GARBAGE!! The problem is the boot is a multi peice and the Ford original is a solid piece. I would recommend the Ford Racing wires, hopefully those are high quality like the originals.
