The MSD 8.5mm Super Conductor Wire is “the” performance wire.Engineered from the inside out, the 8.5 offers everything you have hondacivicmsdeverwanted 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.

The Super Conductor Wire has less than 50 ohms per foot, the lowest available in a helically wound wire. A special copper-alloy conductor is wrapped very tightly around a ferro-magnetic impregnated center core which gives the wire extremely high EMI suppression. This design ensures that optimum spark energy will reach the spark plugs while EMI noise is held at a minimum.

Spark plug wires have two main objectives; transfer the spark energy to the plugs and suppress the Electro Magnetic Interference (EMI) that the spark voltage projects. Too high of resistance decreases the spark energy, yet too low of resistance may generate too much EMI noise which will interfere with the operation of other electronics on the vehicle. A good quality wire, proper routing and routine inspection are all important in getting the most performance out of your ignition system.

If you have a 6AL Ignition and use the car as a daily driver, the wires will last for thousands of miles. Conversely, if you are racing a high compression engine with nitrous and an MSD 10, the wires should be inspected and even replaced during the race season. When checking wires, closely inspect for signs of burning or arc-through. Look at the boots for signs of cracking or burning and using an ohm meter to check resistance of each wire is a good idea. Also, keep in mind that the coil wire is delivering eight times the spark so it should be checked closely. When checking resistance of the wires note that the longer wires will have more total resistance, but their values should average out. If one wire stands out among the others, it should be replaced.

Spark Plug Wires

The spark plug wires are the arteries of the ignition system. They provide the all-important path that allows the spark to transfer from the distributor cap to the spark plugs. The importance of good quality spark plug wires cannot be stressed enough! Plug wires live in a nasty environment and deal with high heat, abrasion, and getting whipped around at high speeds. They also need to be able to deliver high levels of voltage, while suppressing electromagnetic interference (EMI), which is created when high voltage passes through a wire.

 

EMI refers to electrical noise or interference. Not only can it be an annoying buzz through the radio, but it can also wreak havoc on other electronics such as the rev limiter, or even the ECU of a car equipped with an EFI system. Original equipment spark plug wires combat wire cutout-copyEMI by using a carbon core material that has a very high resistance to the flow of the spark energy. The aftermarket offers a variety of wire sets that offer much lower resistance to ensure the most spark possible reaches the plugs.

When you’re shopping for wires, look for lower resistance (measured in ohms), but also look for good EMI suppression. Another area of importance in the spark plug wire is the crimp between the terminal and the wire. Poor crimps can contribute to intermittent performance, a dead cylinder, and other problems. Also pay attention to the spark plug wire boots, as they need to survive parked in close proximity to the exhaust manifolds where heat is at its most extreme.
