Eric, are your OE wires missing? That's why you're buying this used stuff?
JMHO

I replaced my OE wires when I did my injectors and I used a set of magnecore's that I bought on e-bay. They were about 130.00 w/shipping. As Jeff says the stock replacements from GM are just fine too. I don't even miss the "corvette LT5" logo any longer. They have been on there since 9/05, and they work fine on my car.
