You can get up to 50 percent more starting power when you pick Summit Racing™ high-torque mini starters. They're 40 percent lighter, as well as 1/3 smaller. That latter characteristic translates into increased clearance, but both factors can be equally important in a race car. So can features such as full ball-bearing construction, which allows these starters to work great while lasting a long time.

MSD Pro-Billet distributors share the same CNC machining techniques as the rest of the MSD distributor line. They feature a housing that's machined from high-quality 6061-T6 aluminum for durability and show-quality looks. Their oversized shaft receives a QPQ coating for friction reduction and corrosion resistance, with the added strength of two sealed ball bearings that guide the shaft accurately at well over 10,000 rpm. An extra-long sintered bushing replaces the ball bearing at the bottom of Chevrolet models. TIG-welded on top of the polished steel shaft is MSD's accurate mechanical advance assembly. The weights are supported by nylon pads that allow the advance to operate smoothly throughout the rpm range. For all-out racing, the advance mechanism can also be easily locked out. To accurately trigger the ignition, a high-output magnetic pickup is bolted to the base. This pickup produces a precise trigger signal that will never vary more than one degree at any rpm. A durable gear is installed for performance applications, and an MSD red cap with brass terminals and race rotor is supplied. They're available in standard and small diameter models for applications with limited clearance, and require the use of a separate ignition box such as an MSD 6, 7, 8, or 10 Series ignition.

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.
