Detailed Description

The Denso 671-6124 spark plug wire set is engineered for select 1992-1998 Dodge B150, B1500, B250, B2500, Dakota, Durango, Ram 1500, D150, D250, and W150 applications. It is a 7mm ignition wire set designed to match original equipment routing and connection style, including heat shield requirements noted for many listed vehicles. For buyers searching for a Dodge Dakota spark plug wire set, Dodge Ram 1500 ignition wires, or a Denso 671-6124 replacement, this part provides an OE-style solution with factory-fit characteristics.

Denso’s First Time Fit line focuses on matching the original part’s physical design and electrical performance, which helps maintain consistent spark delivery and reliable ignition system operation. This part cross-references NAPA Mileage Plus 6716124 for the same application.

What It Helps Address

• Misfires caused by worn or heat-damaged ignition wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated wire insulation or terminals
• Intermittent ignition performance from cracked boots or poor connections
• Voltage leakage in aging Dodge ignition wire assemblies

Installation Notes and Tips

Verify engine application and wire routing before installation. Several listed Dodge applications require heat shields noted as 2.48 inches long, so confirm the existing setup matches the vehicle-specific notes. Route each wire away from exhaust heat and moving components, and ensure the female terminals fully seat at the coil and spark plug ends.

Quality Assurance

Denso states that First Time Fit ignition wire sets are manufactured to meet or exceed OE/OES standards and are built to mirror factory-installed wire sets in form, fit, color, and performance. Part number 671-6124 is a direct-fit style replacement for the listed Dodge applications.
