Spiro-Pro wire provides up to 10 times the conductivity of standard resistor wire. Provides the highest firepower available without RFI (radio frequency interference). This blue 8mm wire is insulated with two layers of 100% silicone giving superior heat protection up to 600°F.

One end of each plug wire has a straight spark plug end installed; the other end must be cut and terminated to fit the specific application. Includes connectors for both socket style (conventional Bosch / Autolite) and HEI-type (tower) distributor terminals. These sets include a coil wire. Blue only.

Note: The boots on the plug end are not long enough to fit into deeply recessed plug wells. They will not fit most DOHC or Hemi engines.
