Product Details

The Denso First Time Fit line focuses on OE-style replacement parts that mirror the original wire set in form and performance. Part number 671-6222 is made for 1997-1999 Mitsubishi 3000GT models and is a practical choice when restoring ignition reliability on a Mitsubishi 3000GT, especially when the original wire set shows age-related wear. This part cross-references NGK ME78 and MX105 for the same application.

With silicone boots, a 7mm outer diameter, and a 120-degree spark plug end boot, this wire set is built around the fitment and connection details that matter in ignition service. The Denso 671-6222 designation is also useful when searching for a direct replacement by part number.

Common Issues This Part Can Address

• Misfires caused by worn or deteriorated ignition wires
• Hard starting related to weak spark delivery
• Rough idle from inconsistent ignition transfer
• Voltage leakage from cracked or aged wire insulation
• Poor terminal connection at the spark plug or coil/distributor end

Installation Notes and Tips

Verify routing against the original wire layout before installation to maintain proper separation and connection order. Inspect spark plugs, distributor cap, and coil components at the same time, since worn ignition parts can shorten wire life and affect performance. Confirm the 1997-1999 Mitsubishi 3000GT application and match the 7mm wire specification before installation.

Quality Assurance

Denso First Time Fit ignition wire sets are engineered to align with OE/OES standards for construction and performance. The product line is positioned as an OE-style replacement solution for drivers who want factory-like fitment on the Mitsubishi 3000GT.
