Detailed Description

The Denso 671-4114 ignition wire set is part of Denso’s First Time Fit line, which focuses on OE-style replacement parts that match the original wire set’s appearance and performance characteristics. The 7mm wire diameter, silicone boot material, and terminal configuration support proper ignition routing on the listed Toyota applications, including Toyota Celica, Toyota Corona, and Toyota Pickup models from the fitment range shown.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak ignition transfer
• Rough idle from deteriorated wire insulation or boot wear
• Intermittent ignition performance from poor terminal contact
• Voltage leakage from cracked or aged ignition leads

Installation Notes and Tips

Verify wire routing against the original layout before installation. Match the female spark plug end and male distributor/coil end terminals to the vehicle’s ignition connection points, and confirm the 180-degree boot orientation clears nearby components. For Toyota Corona, Toyota Pickup, and Toyota Celica applications, compare the existing wire set length and routing path to the replacement part before final installation.

Quality Assurance

Denso First Time Fit ignition wire sets are engineered to match factory-installed wire sets in form, fit, color, and performance, with construction that meets or exceeds OE/OES standards.
