We manufacture (2) categories of spark plug wires: Exact Reproduction Sets and Replacement Sets.

Exact Reproduction Sets

In order to satisfy the most discriminating enthusiast and restorer, Lectric Limited offers authentic reproduction spark plug wire sets. These sets are identical to the spark plug wires as they would have appeared on your vehicle when it shipped from the factory. They look, fit, and perform exactly as original and provide the finishing touch for any original or restored vehicle. All sets include the coil wire. (See information below on how to order date coded wires.)

  • Manufactured from the original manufacturer (GM, Chrysler, AMC) specifications/blueprints.
  • Wire Conductor: original wire type (carbon-core).
  • Wire Color: original color (black, gray or brick red).
  • Wire Lengths: original wire lengths.
  • Wire Script: original script nomenclature.
  • Wire Script Color: original script ink type and color (white, black or yellow).
  • Wire Braiding: original machine-applied metal braiding (Corvette big block only, if applicable).
  • Wire Manufacturer: original manufacturer (Packard Electric®).
  • Wire Date Code: original date code (if applicable).
  • Terminals: original configuration (45°, 90°, 135° or 180°).
  • Boot Color: original color (black, gray, brown or orange).
  • Boot Type: original size, shape and configuration (45°, 90°, 135° or 180°).

Date Coded Spark Plug Wires

spark plug wire date code
Example of a spark plug wire date code. This code (3-Q-62), means that the wire was manufactured (but not necessarily installed in a vehicle) during the 3rd quarter (July-September) of 1962.

For the restorer, we manufacture date coded spark plug wires.  But what are "date coded" wires?

In January 1961, spark plug wire manufacturers began to print date codes on their wires for their own internal identification (quality control) purposes. Note: 1961 G.M., Chrysler and AMC vehicles built prior to January 1961 did not use date coded wires. Research has shown that most vehicles had wires installed that were dated anywhere from 1 to 4 quarters prior to the build date of the vehicle. That equates to an actual time period of 1 to 12 months. Lectric Limited’s spark plug wire sets are either dated the first (1-Q) or third (3-Q) quarter of each year, starting with 1961. Second and fourth quarter dating is not available at this time, nor should it be necessary due to the wide spread of 1 month to 12 months previously mentioned.

A production run of a particular model vehicle actually began in September or October of the previous year. For example: The first 1962 models vehicles actually left the assembly line in September or October of 1961. Keeping this in mind, you should determine when your car was manufactured and order the date code (year and quarter) for your spark plug wires accordingly. For Corvettes, the serial numbers shown below are the last 5 numbers of the Corvette’s serial/VIN number. This number corresponds to the Corvette’s build sequence number.  For example: 05966 was the 5,966th Corvette to come off the production line that year. You can also determine the recommended spark plug wire date code by the vehicle's build date. This build date applies to all General Motors, Chrysler and AMC vehicles.

Replacement Sets

As an alternative, for the budget-minded restorer, we also manufacture GM and Chrysler "replacement" spark plug wire sets. These are a cost-saving alternative to our factory-original "reproduction" sets.  Our replacement sets have an original look, and fit better on your classic or muscle car than the wires available from an auto part’s store.  Replacement sets are not available for all vehicles.

The differences between a reproduction and replacement set are as follows.  A replacement set has:

  • Wire Conductor: same wire type (carbon-core) as original.
  • Wire Color: same color (black) as original.
  • Wire Lengths: original or longer wire lengths.
  • Wire Script (GM vehicles): uses a current Packard Electric® script.  Not necessarily an original script.
  • Wire Script (Chrysler vehicles): same script as original (not date coded).
  • Wire Script Color: same script ink type and color (black or yellow) as original.
  • Wire Date Code: not date coded.
  • Wire Manufacturer: same manufacturer (Packard Electric®) as original.
  • Terminals: same configuration (45°, 90°, 135° or 180°) as original.
  • Boot Color: same color (black, gray or orange) as original.
  • Boot Type: similar appearance and currently available configuration (45°, 90°, 135° or 180°) to original.
