MSD's 8.5mm Super Conductor wire sets have a special helically wound core that has just 40-50 ohms of resistance per foot--but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire features 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip on cylinder markers, for easy identification. MSD's 8.5mm Super Conductor wire sets come available in custom or universal-fit applications.

Perfect for running wires where you need

Summit Racing Verified Purchase

I have an old 79 blazer that these wires went on. The fact that you get to cut and build these wires the length you need says it all. Any route you need to take with your wires can now be done and they even come with a tool to build them properly. For just a few dollars more these wires were exactly what I needed and they are superb quality. I could instantly feel more power with these. I would recommend this item to anyone who puts quality in their ride. ...read more

Excellent Spiral Core Wire

Summit Racing Verified Purchase

I've used these wires for over twenty years on one vehicle and they have never needed replacement. The boots are great and the wire insulation is also. They won't leak using aftermarket high voltage ignitions as long as they have been assembled properly using the included tool. They also effectively suppress EMF and cross induction. The boot design on this model is also good for small block Chevy angle port heads and most headers. The wire lengths are long enough for a number of wiring arrangements for good wire placement. Both HEI and conventional style distributor boots are supplied in the package with the correct metal terminals. ...read more
