      Vast Improvement!

      As soon as you open the box you can really see the quality of the wires. They are a nice shade of blue and definitely work! Brought my old car back from the dead! Before the wires the car couldn't get past 60 mph, after the wires all of the power came back and wow what a difference! The only issue I had was that some of the wires seemed to be too long, but that's not a huge deal.

      Great quality

      I installed these on my 90 lx 5.0 5spd, and boy I love the color. Had to replace the old spark plug wires part of rebuilding my Fox, and these were an amazing replacement.

      Plug Wires

      Best thing about these wires is that they are number for each cylinder so you don/t have to check the length before hand. Not really adding anything to your engine but some style/color. Still good though.

      Blue Ford Racing Wires

      I installed these blue ford racing wires, I can feel the difference in throttle response. These wires brightened up my engine bay along with the blue distributor cap. I recommend these wires to anybody who wants there engine bay color scheme to be blue... Thumbs up American muscle

      Completely Satisfied

      The moment I took these puppies out of the box I knew they were a quality item and a great purchase. Meaty, snazzy looking, and feel like they'll hold up to several attaches/detaches from the plugs. I gave performance gain 4 stars because upgraded my plugs at the same time but between those two switches my car feels like it just had a cup of coffee. Couldn't be more pleased.

      Ford Racing High Performance 9mm Spark Plug Wires - Blue (79-95 5.0L)

      Good fit and performance,but does interfere with the radio. Looks great, don't fit in stock wired looms so you have to get creative to get them to stay where you want them and not lay on your exhaust. As for the radio....I play CDs most of the time anyway, so no big deal for me.

      Great wires, poor fit for 94-95

      I love these wires but the ones I got said on the box for 5.0/5.8L engines and EVERY wire was anywhere from 3-8 inches longer then the stock 95 GT 5.0 wire(mine still had the original wires on it). The coil wire was obviously made for a fox body car as it was over a foot to long. 94-95 GT owners beware unless you feel like doing a LOT of wire surgery. Such a shame as I really like these wires. AM gave me a discount for my next order so that made me feel a little better.

      Really Great Product, Good Value.

      Cons: I installed these on my '94 GT, and the first complaint I have, Is the wire from the distributor cap to the coil was a bit long, and I ended up wrapping it around the back of the distributor before hooking it to the coil, not a big problem, but it doesn't look as "clean" under the hood, I don't think this would be a problem for Foxes. Also, when first installing, double and triple check yourself that these wire are fully clipped onto the plugs, I was fairly careful myself, and 2 of them still managed to pop off, this being said, a few seconds wiggling them around got them to clip on solid, and I haven't had a problem since. Pros: The fact that these are numbered for each cylinder makes them extremely easy to install. I was surprised after installing these wires, as well as some new spark plugs, at the increase in power I felt. It's not a whole lot, but it's definitely noticeable! They also look great under the hood, (minus being wrapped around the distributor) especially matching my CAI and my blue underdrive pulleys. Overall I'd say it was definitely worth it, and I would certainly purchase them again.

      Restored Power

      The Mustang Gt had a huge loss of power. These wires along with a BBK cold air intake, wow! A huge difference. Went from not peeling out to Thrust, Burst and Roll!! Massive. Recommended. I would also recommend replacing the Distributor cap also.
