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.

Super wire set

Summit RacingSummit Racing Verified Purchase

I really like these wires. Well made, thick and the boots are the best of any I've used. Better than the MSD street fire, Accel and others. The custom fit is the way to go for me and I really appreciated the quality of the crimper supplied. This set has the coil wire also. The only thing I didn't really care for is they used the old HEI style distributor boots with the little nipple that snaps into the retainer ring. Only 500 miles so far but if they hold up they'll be the best bang for the buck I've tried. ...read more

Nice wires

Id tags nice added. Description needs to state that it comes with the mini crimper. Crimper makes it very easy and secure.
