Summit Racing™ Ceramic Ignition Wire Sets

If you're running headers with close tolerances or have an engine bay with little room, Summit Racing™ ceramic ignition wire sets are the cure for burnt and melting boots. Their ceramic coating acts as a heat mirror, reflecting infrared energy and heat away from the plug boot—and it's engineered to resist flaking and peeling. The 8mm spiral core silicone wires deliver maximum energy to the spark plugs with built-in RFI suppression for your street-driven vehicle. These affordably priced wire sets are true performance upgrade replacements for OE types. They're available (assembled or non-assembled) with different terminal and boot ends for fitment on a range of vehicle applications.

MSD Race Tailored Super Conductor Wire Sets

MSD 8.5 mm Race Tailored Super Conductor Wire Sets are designed to specifically fit race engines equipped with headers or MSD distributors. They feature wires that are custom cut to route behind the block, under the headers, and to the spark plugs. This routing gives the engine an extra clean appearance as well as protecting the wires from making contact with the engine. The wires have a special helically-wound core that has just 40-50 ohms of resistance per foot--but with the RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire features 40 feet of tightly wound copper for superior conductivity. A tough 8.5 mm synthetic/silicone jacket over an extra heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, stainless steel terminals feature snap locks to assure a secure fit.
