MSD Heli-Core Spark Plug Wires
The MSD Heli-Core Ignition Wires are perfect for passenger cars, tow vehicles and performance cars. The wires are 8mm and can be relied on to deliver all the high voltage your engine needs! Heli-Core wires feature a stainless steel conductor that is wound around a special glass core. The stainless conductor provides a low resistance path for high voltage to flow while keeping Electro Magnetic Interference (EMI) to a minimum. By winding the conductor around a special glass inner core, the EMI is suppressed inside the wire where it cannot interfere with other electronic devices on your vehicle.
Heli-Core Wires also prevent a phenomenon known as Inductive crossfire. When two wires are routed close to each other and happen to follow the firing order of the engine, the spark from one wire could be induced into the other wire. This would cause the other cylinder to ignite far advanced and will cause detonation. For example, the firing order of a small block Chevrolet is 1-8-4-3-6-5-7-2. Notice that cylinders 5 and 7 are next to each in both the firing order and the in their position in the block. If the spark from the number 5 plug wire is induced into the number 7 wire, a spark will occur in the cylinder causing detonation. Sooner or later engine damage will occur.
MSD Spark Plug Wires prevent inductive crossfire with our special winding procedure and center core material. The EMI and voltage is held within the wire and is transferred only to the plug!
The MSD Heli-Core Plug Wire is available in Universal Kits and Bulk Lengths.
