Not enough bang for the buck, in my oppinion. For the price of these, just get an MSD coilpack for an Escort ZX2, and some Ford Racing 9mm wires for an Escort ZX2. Cheaper than either the screamin' demon, or the nology wires, and just as good as far as I can tell.
THe nology wires where a great investment and i have switched back to 9mm plug wires so i could put my billet spark plug cover back on because the nology wires were to damn thick!!I wish I didnt sell the nology because it really did make an improvement even over 9mm and coil pack!!even dyno proven on the steeda sponsered car only 1hp to the wheels but yet a smoother running car and better mpg!! listen to me because I have owned many of sets of different plugs and wires!! most of these other are gonna down them for their price and just cause they can't afford them they just immediatly cross them off their list as a nice modification!! I am and will soon have nology wires back on my car!!
I have the Live Coil stuff and with the larger spark gap i have 3-5 MPG advantage to regular 9mm wires. You have to use the wires that came with it as it haz a HOT spark and a perticular shape on the boot. I recomend it as it actually did something i can measure. Anyhow why would you give up like that on your spark cover? Get some risers and longer bolts and you are in businness.....
