Denso 671-8002 Ignition Wire Set

Denso 671-8002 is a 7mm spark plug wire set built to match factory-installed wire sets in form, fit, color, and performance. It is a direct OE-style ignition wire replacement for drivers searching for a Denso spark plug wire set for Honda Civic, Toyota Corolla, and similar ignition service applications.

Key Features

  • 7mm insulation outside diameter for OE-style ignition wire routing and fit
  • Silicone spark plug boot material for heat resistance and flexibility
  • 180-degree spark plug end boot design for tight engine bay routing
  • Female spark plug end terminal type with male distributor/coil end terminal
  • Built to meet or exceed OE/OES standards in construction and performance
  • Direct replacement part number 671-8002 for ignition wire service

Product Details

Denso’s First Time Fit ignition wire line is engineered as an OE replacement for vehicles that require precise wire length, terminal style, and boot configuration. The 7mm wire diameter supports stable ignition routing, while the silicone boot material helps maintain a secure connection at the spark plug end. This Denso 671-8002 spark plug wire set is a practical choice for technicians and owners replacing worn ignition leads on import vehicles such as Honda Civic and Toyota Corolla applications where OE-style fitment matters.

This part cross-references NAPA Mileage Plus 6718002 and Bosch 09757 for the same application.

What It Helps Fix

  • Misfires caused by cracked or deteriorated ignition wires
  • Hard starting related to weak spark delivery
  • Rough idle from inconsistent ignition voltage transfer
  • Engine hesitation under load from worn wire insulation
  • Intermittent ignition performance from loose or damaged terminals

Installation Notes

Match each wire to the original routing before removal to preserve firing order and prevent crossfire. Confirm the distributor or coil end uses a male terminal and the spark plug end uses a female terminal with 180-degree boot orientation. Inspect plugs, cap, and coil components during service so the new wire set is installed into a clean ignition system.

Quality Assurance

Denso First Time Fit ignition wire sets are produced to align with OE/OES standards for construction and performance. The 671-8002 part number identifies this OE-style replacement wire set for accurate ordering and service verification.
