Will fit smallblack also.
/BR>Tune-up your entire ignition at once with Summit® Volt Max X-TREME spark plug wires/cap and rotor kits.
/BR>They're made to handle extreme conditions while perfectly matching OEM specs.
/BR>The ultra-low resistance wire core is wrapped in a high dielectric capacitance jacket to keep voltage directed to the plug, and is protected by a tough silicone outer jacket.
/BR>Stainless steel terminals (solid brass for Ford D.I.S. applications) with hardened, positive snap-locks ensure a permanent connection, and the silicone boots can handle up to 450 degrees F of heat.

The wire sets include dielectric grease to seal terminals and boots, plus wire separators (a must if your OEM wire are 7mm).
