MSD Spark Plug Wires

Super Conductor Spark Plug Wire is the ultimate performance plug wire. The wire's extremely low resistance with high Electro Magnetic Interference suppression is a combination that defies the common laws of physics.

Less resistance means more energy is delivered to the plugs which helps burn the fuel mixture more complete and complete combustion means more power. With less than 50 ohms per foot, the 8.5mm wire is capable of delivering 30 times more spark energy to the plug over most OEM wires?

This low resistance is produced due to a special copper alloy conductor. The copper-alloy material has excellent voltage carrying capabilities as well as strength. This conductor is then tightly wrapped around a ferro-magnetic impregnated center core. So tightly in fact, that for every single foot of wire there is 40 feet of conductor windings! This combination is responsible for suppressing EMI noise to the equivalent of a 1,500 ohm per foot wire.

The outer sleeve of the Super Conductor is just as impressive as the conductor. MSD uses a proprietary combination of silicone and synthetic material producing a wire with resistance to high heat, tearing and chemicals. The tough sleeve also provides a solid foundation to crimp the terminals, delivering the highest terminal pull-off strength of any other performance wire.

Many different custom length sets are available as well as universal sets that you custom tailor to match your application. When it comes to the plug wires, the 8.5mm Super Conductor Wire delivers everything you want in a wire.

Protect your spark plug wires from high temperatures with an MSD Heat Guard Kit. The Kit features two special heat resistant sleevings that are woven from layered quartz-glass fiber. One sleeve protects the wire while another sleeve protects the spark plug boot. Special glass cords and no-split shrink sleeving are used to secure the sleeving on the wire.

MSD's Pro-Boot Guard is designed to protect spark plug boots from excessive heat. The slide-on sleeve features a fiberglass woven inner sleeve which is then coated with a specially compounded silicone rubber. This combination produces a thick sleeve that can withstand extreme temperatures. Slides over most plug boots.

Pro-series wire separators are constructed from high temperature ABS to be both oil and fuel resistant while providing the ultimate protection against harmful ignition crossfire.  Each separator bolts together for a positive clamp fit.  Each set consists of two each 4 wire, 3 wire and 2 wire separators.
