NGK Buick Century 1991-1989 Spark Plug Wire Set

When it’s time to replace the spark plug wires on your 1989-1991 Buick Century, you want a set that’s built to last and deliver a strong spark. These NGK wire sets are designed to do just that, ensuring your engine runs smoothly and efficiently. They fit a range of vehicles, including many Buick, Oldsmobile, and Pontiac models from the early to mid-90s.

What sets these wires apart is their ultra-low resistance mag core construction. This means less energy is lost before it reaches the spark plug, resulting in a more powerful spark. The wires also feature a high-temperature silicone outer jacket and EPDM/silicone inner insulation, which helps contain the high voltage and provides excellent dielectric strength. You’ll also find that the OE-specified boots fit securely, and the stainless steel terminals offer strong retention, keeping everything connected even in tough conditions. Plus, the spark plug boots are sealed to the cable with silicone for a watertight connection.

NGK is known for making reliable ignition components, and these wire sets are no exception. They are a solid option for restoring your engine's performance and ensuring consistent ignition.
