NGK Spark Plug
NGK is a Japanese company and a global leader in ignition technology and sensors for internal combustion engines. The company's history dates back to 1936, when NGK Spark Plug Co., Ltd. was founded in Nagoya, Japan. Less than a year later, the young company began supplying its first spark plugs, which remain a cornerstone of its product range today.
By the 1950s, the company's offering expanded to include new NGK products, such as technical ceramics used in various industrial applications. In 1958, NGK established the NTK brand, focusing on manufacturing cutting tools and ceramic components. Today, this division remains a vital part of the company’s industrial operations.
With the introduction of catalytic converters, NGK incorporated lambda sensors into its portfolio. Ongoing product and technology development enabled the company to expand into European and American markets. In 2015, NGK acquired Wells Manufacturing, a leading global producer of automotive electronics. Today, the NGK Spark Plug Group employs over 16,000 people, operating through 43 subsidiaries, 33 production facilities, and 5 technology centres.
NGK Products Deliver Precise Ignition in Petrol Engines
Every petrol engine relies on a well-functioning ignition system. The spark generated by NGK products ignites the fuel-air mixture, ensuring efficient engine performance. This process requires precision and durability to withstand demanding operating conditions.
With decades of experience and continuous investment in research and technology, NGK has developed over 1,000 types of spark plugs, each designed to deliver optimal performance under a wide range of thermal loads. This ensures high thermal resilience and efficiency.
Spark plugs are NGK products frequently chosen by vehicle manufacturers as original equipment. The company also dominates the independent aftermarket for automotive parts. With over 1,500 models available, NGK spark plugs cover 93% of vehicles on European roads.
NGK Products: Essential Sensors for Engine Efficiency
The lambda sensor, often called the oxygen sensor, is one of the most critical components ensuring proper engine performance. It monitors exhaust gas composition, allowing the engine to operate efficiently while minimising harmful emissions. NGK excels in producing high-quality lambda sensors, ensuring vehicles perform optimally and adhere to environmental standards.
NGK products also include additional sensors vital for the proper functioning of modern engines. These range from exhaust gas temperature (EGT) sensors and EGR valves for exhaust gas recirculation systems to pressure sensors and air flow meters.
Choose NGK for reliable, high-quality products that optimise engine performance while reducing emissions.
