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.

Holley LS Modular Lo-Ram EFI intake systems have a top-feed plenum entry configuration, designed to allow the currently available Hi-Ram 105mm plenum tops to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications and was conceived to package with an air-to-water plenum-mounted intercooler—with a shorter overall height than is possible with other existing intake manifolds. Using a modular design, the top-feed plenum configuration with 105mm top keeps the overall height at just 9.07 in.! Additional features and specs include: * Cast aluminum construction * Modular design allows the use of the included top-feed plenum entry * Designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) cylinder heads * Will also work with OE or aftermarket cylinder heads * Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7,000 to 8,000 rpm, depending on application * Low height to aid the packaging of a plenum-mounted air-to-water intercooler in a top-feed configuration (or to fit under a stock or mildly modified hood in the front-feed configuration) * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits come with two sets of brackets—a set for long (usually standard length) fuel injectors, and a set for short (such as Pico or LS7) fuel injectors
