About the NGK Laser Iridium Spark Plug Line

The Laser Iridium Spark Plug line from NGK is designed to provide precise ignition performance and extended durability. Iridium, being a hard and corrosion-resistant metal, allows for a finer electrode tip that requires less voltage to generate a spark. This results in improved combustion efficiency and reduced misfires. The combination of iridium and copper core materials in this product line balances longevity with excellent electrical conductivity, making it suitable for many domestic and imported vehicles.

Compatible Vehicles and Applications

This NGK Laser Iridium Spark Plug 97287 is compatible with a broad range of vehicles, including models from Ford, Chevrolet, Cadillac, Lincoln, Buick, Pontiac, and Aston Martin. It fits popular models such as the Ford F-150, Chevrolet Camaro, Cadillac DeVille, Lincoln Continental, and Buick Regal, among others. This part number is ideal for secondary ignition system replacements where precise spark delivery is critical.

• Resolves engine misfires and rough idling
