    Recommended by Rossini Racing Engines and 5X Racing! We use and recommend this plug wire set to anyone because of its secure plug boots and comforting "snap" fit when you install them. Other plug wires we've used have not given us a confident "snap" onto the plug or coil, but the MSD wires do, and we like that. The plug boots are also moulded one-piece construction, which is also a good thing for a racecar, as it limits the chances of something wiggling loose.

    Manufacturers Info:
    Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12 inch length of Super Conductor Wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears.
