Spark plug wire sets

Many American Autowire spark plug wire sets are available in two categories. Either one will do just fine to get your plugs firing, but there are some differences.

Factory original reproduction plug wire sets (Date Coded):

Date coded wires are exact replacements for what would have been in the vehicle when it shipped from the factory, and will have the original GM date code printed on each wire lead.

Non-date coded replacement wire sets:

Our replacement wire sets are assembled using Packard wire, and use currently available replacement spark plug boots. Replacement sets do not have date code information printed on the wire. Fit, appearance and function are substantially better than current GM replacement sets. These are a great option for the budget-minded restorer.

Both types of wire can be found in our Factory Fit catalog.
