NGK Ignition Coil V6 Replacement 1985-2005 Buick Century

NGK Ignition Coil V6 Replacement 1985-2005 Buick Century restores a strong, consistent spark to the engine, improving ignition reliability and reducing misfires for smoother operation.

The engine’s basic requirements are fuel, air, compression, and spark. This replacement ignition coil addresses the spark element directly — replacing a weak or failing coil to help recover proper combustion behavior and engine responsiveness. A degraded coil can lead to misfiring, rough idle, and reduced drivability; installing a direct-fit replacement helps return the ignition system to its intended performance.

Function and value

This coil is intended as a direct replacement for the factory unit on compatible Buick Century V6 applications from 1985–2005. By restoring consistent high-voltage delivery to the spark plugs, it supports stable combustion timing and reduces the symptoms associated with ignition weakness.

Why this matters

• Consistent spark delivery — Ensures each cylinder receives the voltage needed for reliable ignition, which matters for smooth idle and reduced misfire codes.
• Direct-fit design — Minimizes installation time and reduces the need for modification, preserving original routing and mounting for reliable service life.
• Maintenance-first approach — Replacing worn ignition components before performance upgrades ensures the engine’s fundamental systems are operating correctly.
