I also recommend Firecore. 2 things to keep in mind if you want the stock look. The wires are more of a dark grey then black. Since they are 8mm, if you want to run them through the factory looms you will need to open all the holes a little with a rat tail file or a hand auger.

Thanks much, guys. The new 7mm wires are a perfect fitting, high performance, low ohm wire. They will not give off any radio noise as well. Thanks, Rick Gorski
