Detailed Description

Denso 671-6122 is a spark plug wire set for vehicles that require a 7mm ignition wire layout and factory-style terminal fitment. It is listed for applications such as 1975-1980 Dodge B100, 1975-1980 Dodge D200, 1975-1980 Dodge Ramcharger, 1978-1981 Chrysler LeBaron, and 1981-1987 Dodge D150. Additional coverage includes Dodge B150, B250, D250, W150, W100, Plymouth PB150, PB250, and Chrysler Fifth Avenue among other listed vehicles.

This part cross-references ACDelco 16-806A and Bosch 09289 for the same application. If you are replacing worn ignition wires on a Dodge D100, Dodge W200, or Chrysler Newport, Denso 671-6122 provides the OE-style dimensions and connector layout needed for a direct service replacement.

Common Problems This Part Addresses

• Misfires caused by aged or damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from cracked insulation or poor terminal contact
• Intermittent ignition performance from heat-damaged boots
• Voltage leakage across worn wire insulation

Installation Notes and Tips

Verify engine application, routing, and terminal style before installation. Match each wire to the original routing path to avoid crossfire and heat exposure. Inspect distributor cap, coil connection, and spark plugs at the same time so the new wire set can perform as intended. For vehicles listed with 7mm ignition wire requirements, confirm that the replacement follows the original connector orientation and boot angle.

Quality Assurance

Denso states that First Time Fit ignition wire sets are built to match factory-installed wire sets in form, fit, color, and performance, with construction that meets or exceeds OE/OES standards.
