MSD 8.5mm Super Conductor Spark Plug Wire Sets

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 Steel Distributor Gears

MSD's high-grade steel distributor gears are burnished for a smooth, scuff-free finish, and are machined for precise gear mesh. Excessive clearance causes timing fluctuation throughout the rpm range, resulting in lost horsepower, so MSD also designed these gears for tighter mesh between the camshaft and distributor drive gears.

Proform Street/Strip HEI Distributors

Proform's Street/Strip HEI distributors have a variety of improvements over stock HEI distributors, such as a 50,000 V coil, a premium hi-dielectric cap with brass terminals, both upper and lower bushings for added durability, a low-saturation ignition module, and no voltage-reducing ballast resistors. These units offer calibrated advance curves that are optimized for maximum combustion efficiency, and the elimination of detonation damage and throttle ping. The distributors offer longer-term durability and a higher voltage spark that permits a bigger spark plug gap, resulting in more power and reduced plug fouling. The Ford models' internal coil and module make it possible for Blue Oval owners to avoid the unsightly wiring of stock Ford electronic ignitions. By eliminating the stock Ford or AMC ballast resistor, you'll get more ignition voltage, resulting in an improved spark. Another advantage to switching to HEI is access to easily-found HEI replacement parts. The Ford units are also assembled with upper and lower bushings, an upgrade from stock distributors that only have a single bushing. They're easy to install by connecting one 12 V hot wire to the distributor, making them a quick performance upgrade.
