Q & A

What's in the Box

What makes or breaks a plugwire is not only how well the wire is insulated, but how low of resistance the center core has.  These wire sets test 40-50 ohms per foot, while most others test 1500 ohms per foot. Low Resistance

These plug wires do require assembly although the plug end is alread installed.  Both HEI and socket style distributor ends are supplied.
