MSD Race Tailored wire sets are designed specifically to fit race engines equipped with headers or an MSD Distributor. - Wires go below headers/exhaust manifolds
- For MSD Distributors 121-8489 and 121-84891Crab Cap 121-8541
- Less than 50 OHMS per foot for superior spark
- Ferro-magnetic impregnated core creates an effective EMI choke
- Forty feet of conductor is wound into a single foot of wire for high EMI suppression
- Conductor core features Dupont Kevlar material for increased tensile strength
- Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion
- MSD Heli-Core Ignition Wires are perfect for passenger cars, tow vehicles and performance cars. These 8mm spark plug wires 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. 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!
Dual Crimp Terminals All of the MSD spark plug terminals feature ''Dual Crimp'' terminals. One for the sleeve of the wire and another separate crimp to grasp the conductor of the wire. By having separate crimps, the conductor doesn't need to bent 180° and get squeezed between the terminal and sleeve. The individual conductor crimp produces a more secure crimp and there is less chance of spark arcing to the engine block or exhaust through the boot. In fact, every factory crimped plug wire is guaranteed not to ''pull off'' for FIVE years!
