Fits select 2000-2005 Buick, Chevrolet, Oldsmobile, and Pontiac models including Century, Impala, Grand Am, and Montana.

The NGK 51021 Spark Plug Wire Set is engineered to provide maximum conductivity while maintaining excellent EMI/RFI noise suppression. These ultra-low resistance mag core wires utilize a premium ferrite magnetic core wrapped in stainless steel winding to deliver a more powerful spark to the combustion chamber. To withstand the harsh environment of the engine bay, each wire is protected by a high-temp silicone outer jacket and inner EPDM/silicone insulation, providing superior dielectric strength against high voltage leaks.

• Mag Core Construction: Ferrite magnetic core with stainless steel winding for low resistance and high-energy delivery.
• Heat Protection: Premium silicone outer jacket rated for high engine temperatures.
• Watertight Seal: Spark plug boots are factory-glued with a silicone sealer to exclude moisture and prevent arcing.
• Secure Retention: Stainless steel terminals feature up to three serrated crimps for high retention strength, paired with a corrosion-resistant C-shaped spring clip for a positive connection.
• Interference Suppression: Integrated suppression layers prevent electrical noise from affecting onboard electronics.
• Manufacturer Part Number: 51021
