What It Helps Address

• Misfires caused by aged or heat-damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from poor wire insulation or terminal wear
• Intermittent ignition performance from loose or degraded connections
• Voltage leakage across cracked or deteriorated plug wires

Installation Notes and Tips

Verify engine layout and wire routing before removal so each lead returns to the correct cylinder and coil/distributor connection. Inspect spark plugs, coil terminals, and routing clips for wear before installing the new set. The 90-degree spark plug boots help with clearance in tighter spaces, and the female spark plug terminals and male distributor/coil end terminals should be matched carefully during installation.

Quality Assurance

Denso First Time Fit ignition wire sets are built to meet or exceed OE/OES standards and are produced to mirror factory-installed specifications for fit and performance. The 671-6202 part number is intended as an OE-style replacement for the listed Nissan applications.
