Contour Enthusiasts Group Archives Forums Modifications Duratec Performance hyperground wires??

I just got some on my ride. I didn't use the whole set up just 3 parts. It hard to say without a dyno but I think it a good product. Some of my friend got there cars(hondas) dynoed after install and they had between 5 and 8 hp gains.Where some had none just depends on how well there grounded from factory.. If I fined something out on mine I'll let u know
