        High quality!

        I have old 8mm "Ford Motorsport" wires from the 90's these 9mm are just as high quality as the old set. Should last forever! This set is NOT replacing the old set. These are going on my bronco with a CHP 408W

        Nice upgrade over your stock wires.. Thanks A.M !

        Bought these wires to go with the NGK Plugs.. Happy with the purchase and service of American Muscle. Don't expect any hp gain however the start up and idle is alot smoother..Thanks A M !!

        Look great

        Wires look and fit great. I originally bought some cheap wires but had a lot of random misfiring and found out the cheap wires with less than 5k were cross firing and arching. Bought these ford racing wires and I have all my power back and no more misfiring. I recommend getting some good wire looms and taking the time to run these as good as possible considering they seem like they’re a little too long in some areas but some looms took care of that no problem.

        Poor fit

        Wires appear to be great quality. But they are very long. I like my wires tight and nicely ran. I will be cutting ALL of the wires and re-terminating them to get them to fit right.
