Would bigger plug wires make any difference my stockers look pretty thick already and aren't dried out or worn.
How about the coil pack, worth upgrading?

Thanks

the short answer?? NO, the stock components are more than capapble!!

I still have the originals on both 01 wagons I have no cracks no ignition probs and dirty as hell to boot, but still work great LOL

I had oversized then went to performance on my old car but honestly it made my old car run like utter crap so I dug the old ones out of the trash bin ( OEM Original Stock 12 year old Wires) and threw them on with new plugs and it ran like new ( pretty much Im sticking with stocks) unless they have a ford racing set specific to the Zetecs XD
