Denso 671-4067 Spark Plug Wire Set

Denso 7mm Spark Plug Wire Set 671-4067

Denso 671-4067 is a 7mm spark plug wire set built to match factory-installed wire sets in form, fit, color, and performance. It is a direct replacement for Chrysler, Dodge, and Plymouth applications that use a 7mm ignition wire design, including Chrysler LeBaron, Dodge Caravan, and Plymouth Voyager models.

Key Features

• 7mm insulation outside diameter for OE-style ignition wire routing and fit
• Silicone spark plug boot material for heat resistance and durability
• Female spark plug end terminal type with 180-degree spark plug end boot
• Male distributor or coil end terminal type
• Built to meet or exceed OE/OES standards
• Direct-fit replacement for select Chrysler, Dodge, and Plymouth vehicles

Product Details

The Denso First Time Fit product line focuses on OE-style replacement parts that mirror the original wire set in appearance and performance. Part number 671-4067 is engineered for vehicles that require a 7mm ignition wire set, with silicone boots and terminal configurations that match the factory layout. This makes it a practical choice for restoring ignition performance on older Chrysler, Dodge, and Plymouth platforms such as Dodge Aries, Chrysler New Yorker, and Plymouth Reliant. This part cross-references NAPA Mileage Plus (e.g., 6714067) for the same application.

What This Part Helps Address

• Engine misfire caused by worn or damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from inconsistent ignition voltage transfer
• Crossfire or spark leakage from deteriorated wire insulation
• Heat-related boot breakdown in aging ignition systems

Installation Notes and Tips

Verify wire routing against the original layout before installation to maintain proper firing order and separation. Confirm the distributor or coil end and spark plug end terminal types match the vehicle’s ignition system. For fitment reference, this set fits 1981-1989 Dodge Aries, 1982-1990 Chrysler LeBaron, 1984-1990 Dodge Caravan, 1984-1990 Plymouth Voyager, and other listed Chrysler, Dodge, and Plymouth 7mm applications. Part number 671-4067 should be matched to the vehicle’s engine and ignition configuration before purchase.
