What brand is NGK spark plug?

[HenryDella]

NGK is actually a brand originating from Nagoya, Japan. Established in 1936, it initially focused on manufacturing spark plugs. Later in 1949, NGK Company expanded into NTK precision ceramics manufacturing. Over the years, NGK's business has expanded beyond Japan's limited territory and reached out to the world. The characteristics of NGK spark plugs are as follows: Feature 1: Ultra-wide range spark plugs. To dissipate a large amount of heat quickly, copper cores are embedded near the front end of the center electrode, creating a copper-core embedded structure. This design achieves ultra-wide range spark plugs that are resistant to burning and carbon deposits. Feature 2: Uses new ceramic high-alumina ceramics as the insulator. It has excellent insulation at high temperatures, ensuring reliable spark generation. It also has outstanding thermal conductivity, preventing excessive combustion, and strong resistance to thermal shock (rapid heating and cooling), along with high mechanical strength. Feature 3: Precision construction with excellent airtightness. The insulator and main metal are connected using special powder, ensuring excellent airtightness and a robust structure.
