NGK

The NGK category covers ignition components designed to deliver reliable starts and smooth combustion across diesel and gasoline engines. It includes glow plugs for cold-weather starts and a wide range of spark plugs for everyday driving, performance applications, and specialized builds. Within this family you'll find copper-core, iridium, and standard-heat designs, along with variants like V-Groove and Iridium IX. These parts come in common thread sizes (10, 12, 14 mm) and varied heat ranges, with many models pre-gapped for straightforward installation.

Typical uses span passenger cars, light trucks, motorcycles, agricultural equipment, and industrial machinery. Glow plugs warm the combustion chamber for diesel starts, while spark plugs provide reliable ignition and efficient combustion in petrol engines and performance builds. When choosing NGK parts, match engine type, thread size, heat range, and lifecycle expectations. Iridium and copper-core options balance durability with cost, and OEM or cross-reference compatibility helps ensure a precise fit.

For authentic NGK components and guidance, trusted retailers like The Green Spark Plug Company offer a wide selection and technical help to select the right glow plugs and spark plugs for your engine.
