Product Details

The Denso First Time Fit line is engineered as a direct replacement for original ignition wire sets, with dimensions and terminal styles matched to the factory application. Part number 671-6192 is specified for 1993-1998 Mercury Villager and 1993-1998 Nissan Quest models, making it a practical choice when replacing worn ignition wires on these vehicles. This part cross-references NGK (e.g., NX04) and Bosch (e.g., 09348) for the same application.

The wire set uses Sil-PBT-Sil boot construction, a 90-degree spark plug end boot design, and female spark plug terminals to support proper connection at the plug end. The 7mm insulation diameter helps maintain the original routing and clearance expected in the engine bay of the Mercury Villager and Nissan Quest.

Common Issues This Part May Address

• Misfires caused by aged or damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from inconsistent ignition transfer
• Engine hesitation under load from worn wire insulation
• Voltage leakage from cracked or deteriorated boots

Installation Notes and Tips

Verify wire routing against the original layout before removal so each lead returns to the correct cylinder and coil/distributor connection. Inspect plug wells, terminals, and adjacent ignition components for corrosion or heat damage before installing the new set. Confirm the vehicle application by year and model before purchase, especially on 1993-1998 Mercury Villager and Nissan Quest vehicles.

Quality Assurance

Denso First Time Fit ignition wire sets are built to meet or exceed OE/OES standards and are made to match factory-installed wire sets in appearance and performance. Part number 671-6192 is manufactured for direct replacement use on the listed applications.
