MSD 8.5mm Super Conductor spark plug wire sets feature 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 includes 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 are available in custom or universal-fit applications, assembled or not, with a variety of terminal and boot end options.

If you're running headers with close tolerances or have an engine bay with little room, Summit Racing™ ceramic ignition wire sets are the cure for burnt and melting boots. Their ceramic coating acts as a heat mirror, reflecting infrared energy and heat away from the plug boot—and it's engineered to resist flaking and peeling. The 8mm spiral core silicone wires deliver maximum energy to the spark plugs with built-in RFI suppression for your street-driven vehicle. These affordably priced wire sets are true performance upgrade replacements for OE types. They're available (assembled or non-assembled) with different terminal and boot ends for fitment on a range of vehicle applications.
