        1 1997 Cobra - Al Installation Time: Less than 1 Hour

        No Warranty

        Purchased and installed this wire set in January of last year. Car ran well last summer and for about a week after being taken out of storage this summer. Car developed a cylinder two misfire and upon inspection noticed a hole in the number two wire boot causing the spark to arc to the valve cover instead of the plug. These appear to be of excellent quality, but it's disappointing that there is absolutely no warranty and that there was a failure in less than 15k miles of use.

        Good choice!

        Easy to install fit great the factory wire dividers did not fit but I figured being 9mm over all definitely recommend.

        Great product

        My car had a horrible miss at low rpm. I installed these and my car runs better than it ever has. Plus the red color looks great.

        2 1996 Cobra - SteveK Installation Time: Afternoon


        I installed a set of the Blue Ford Performance wires a couple of years back. A few months ago I had an engine misfire due to a bad wire. I decided to get a new set, red ones this time. Also put in all new plugs. A couple of months later a new misfire started to develop. I replaced one wire with an old one. A week later, another misfire. I replaced another wire with an old one. Not sure if I should buy another set.

        4 1996 Cobra - MobiusStrip Installation Time: Less than 1 Hour

        Sturdy, but the "custom" fit isn't quite right.

        This is my second set of Ford wires, and I've encountered the same problem on both: two of the wires are way too long. And it isn't that I'm using them in the wrong position; there aren't any other wires that I could swap them with to achieve a better fit. Strage. They work fine. I think I may have had 8mm wires before, which clipped more securely into the retaining clip at the front of the engine. These are a little too beefy to snap in securely, but no big deal. You'll probably want to do a little zip-tie or Velcro-band work to tidy up the overly-long wires anyway.

      Do I need to request a new tune for these if I already have a tune for other upgrades and 8mm wires?

      • Spark plug wires do not require a new tune.

      Will these wires fit into my stock wire looms for 8mm wires? If not, do you know a good place to get new looms? I've seen a lot on the web, but would prefer a ford product.

      • I had no problems using my 8mm looms. Its a tight fit but its does the job.
