Key Features

• 8mm insulation outside diameter for OE-style wire routing and protection
• Silicone spark plug boot material for heat resistance and flexibility
• 115-degree angled spark plug end boots for proper connection geometry
• Female spark plug end terminal type
• Male distributor/coil end terminal type
• Built to meet or exceed OE/OES standards

Product Details

The Denso First Time Fit line focuses on factory-matched ignition components, and part number 671-6089 follows that approach with OE-style dimensions and terminal design. The 8mm wire insulation supports stable routing in the engine bay, while the silicone boots help maintain connection integrity under heat and vibration. This spark plug wire set is a practical choice for 1996-2000 Ford Taurus and 1996-2000 Mercury Sable models when restoring ignition performance and replacing worn plug wires.

This part cross-references ACDelco 16-816V and Bosch 09743 for the same application.

What It Helps Address

• Misfires caused by worn or damaged ignition wires
• Hard starting related to weak spark delivery
• Rough idle from inconsistent ignition transfer
• Voltage leakage from cracked or deteriorated wire insulation
• Heat-related boot breakdown at the spark plug connection

Installation Notes

Verify engine application before installation and route each lead to match the original wire layout. Confirm secure seating at the spark plug and distributor or coil terminals, and inspect adjacent ignition components for wear before completing the repair. For fitment reference, this part fits 1996-2000 Ford Taurus and 1996-2000 Mercury Sable.

Quality Assurance

Denso positions the First Time Fit line as an OE-style replacement range, with construction that meets or exceeds OE/OES standards. That makes Denso 671-6089 a specification-driven option for ignition wire replacement on Ford Taurus and Mercury Sable vehicles.
