Denso 671-8112 Spark Plug Wire Set

Denso 7mm Spark Plug Wire Set

Denso 671-8112 is a 7mm spark plug wire set built to match factory-installed form, fit, color, and performance. It is a direct replacement for select Chrysler and Dodge applications, including Dodge Dakota and Dodge Ramcharger models from the late 1980s and early 1990s.

Installation Notes and Tips

Verify engine application and wire routing before installation. Match each lead to the original routing path to avoid crossfire and ensure proper ignition timing delivery. Inspect distributor cap, coil connections, and spark plugs at the same time, since worn ignition components can shorten wire life. Confirm fitment for your exact Dodge or Chrysler model before ordering, especially on Dodge Dakota, Dodge Ramcharger, and Chrysler Fifth Avenue applications.
