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.

MSD Digital GM high-energy modules with rev limiters allow you to adjust the rpm limit between 5,000 and 9,000 rpm. True high-performance modules built for HEI distributors, they produce 50 percent higher coil drive currents than the stock module. This saturates the coil faster, which gives you more spark energy at top speeds. The results are increased horsepower and rpm range, and improved starting. When used with MSD's HEI coil, these plug-in modules create a potent high-energy spark to 9,000 rpm. MSD GM HEI modules replace all 4-pin modules used in HEI distributors with a vacuum advance canister. They can be used with factory, aftermarket, or MSD HEI distributors.

MSD puts their years of experience to work in making these top-notch iron camshaft mounted distributor gears. Their high-grade ductile iron is micro-polished for a smooth and scuff-free finish, and then Melonite QPC coated to reduce friction and initial wear. Excessive clearance causes timing fluctuation throughout the rpm range, resulting in lost horsepower, so MSD also designed these iron camshaft mounted distributor gears for tighter mesh to the distributor gear.
