NGK V-Power Spark Plug TR4 (Box of 4) - Select GM 1987-2011

Fits select 1987-2011 Buick, Cadillac, Chevrolet, Oldsmobile, Pontiac, and Saturn models.

NGK V-Power spark plugs are engineered to provide improved ignitability and reliable performance over standard nickel plugs. The specialized design features a V-cut nickel alloy center electrode and a concave ground electrode, which moves the spark to the edge of the electrode to facilitate a quicker, more efficient burn. This results in faster starts, a smoother idle, and enhanced throttle response in OE applications.

• V-Cut Center Electrode: Increases ignitability by reducing quenching and directing the spark to the edge.
• Trivalent Metal Plating: Delivers superior anti-corrosion and anti-seizing properties, ensuring easy installation and removal without anti-seize.
• High-Grade Ceramic: Pure alumina silicate ceramic insulator provides superior dielectric strength and heat transfer.
• Copper Core: Aids in rapid heat removal to prevent pre-ignition.
• Corrugated Ribs: Prevents flashover to ensure consistent ignition.
• Triple Seals: Prevents combustion gas leakage for maintained cylinder compression.
• Quantity: Box of 4
• Part Number: TR4
