NGK V-Power Spark Plug (UR4) - Box of 4 - Select Buick, Cadillac, Chevrolet 1980-1993

Fits select 1980-1993 Buick, Cadillac, and Chevrolet vehicles, including high-performance applications like the Buick Regal Grand National, GNX, and Chevrolet Camaro Z28.

NGK V-Power spark plugs (UR4) are engineered to provide improved ignitability and reduced quenching compared to standard nickel plugs. The specialized V-cut nickel alloy center electrode directs the spark to the edge of the electrode, where it can develop more quickly to increase throttle response and ensure smoother idling. These plugs are an ideal replacement for OE applications requiring a copper core plug with enhanced combustion efficiency.

• V-Cut Center Electrode: Enhances ignitability by focusing the spark kernel for more complete combustion.
• Trivalent Metal Plating: Provides superior anti-corrosion and anti-seizing properties without the need for anti-seize during installation.
• High-Grade Alumina Silicate Ceramic: Ensures high-strength dielectric performance and optimal heat transfer.
• Copper Core: Deeply inserted copper core aids in heat removal to prevent pre-ignition.
• Triple Seals: Prevents combustion gas leakage past the shell.
• Corrugated Ribs: Design prevents flashover to ensure consistent spark delivery.
• Part Number: UR4
• Quantity: Box of 4
