does it really matter what ignition wires i get as long as they're new and not coroded? is it worth it to spend twice as much ($85 compared to $45) on the Ultra wires as opposed to NGK? and does anyone know where the cheapest place to get these would be?

I current have BOSH PREMUIM 7mm plug wires: http://www.partsamerica.com/PartDeta...e=5004&PTSet=A

And they seem to work great. Don' think there is enough gain to spend so much money on ULTRA plug wires if your still using Stock ignition system, I think you should be fine with NGK or another good quailty plug wire.
