What It Helps Address

• Rough idle from inconsistent ignition output
• Voltage leakage from cracked or deteriorated insulation
• Poor terminal contact at the spark plug or coil end

Installation Notes and Tips

Verify wire routing against the original Ford Mustang layout before removal. Match each lead to the correct cylinder and confirm the 135-degree spark plug boots seat fully on the plugs. Inspect coil and distributor connections for corrosion or carbon tracking before installing the new set. For best results, replace one wire at a time or label the original routing to preserve firing order.

Quality Assurance

Denso First Time Fit ignition wire sets are built to meet or exceed OE/OES standards for construction and performance. The 671-8101 is intended as an OE-style replacement for 1996-1998 Ford Mustang ignition service.
