Denso, founded in 1949 as Nippon Electrical Equipments Co., Ltd, is one of the leading companies in the world in the field of automotive components manufacturing. A key moment in its history was the separation from Toyota Motor Co., Ltd and its establishment as an independent business. However, the collaboration with Toyota continued even after this, allowing Denso to remain one of Toyota's main suppliers.

From the beginning of its operations, the company aimed to create high-quality products. The strategy of innovation and product improvement was key. Denso engineers developed the world's first spark plugs with a platinum electrode and a ceramic spark plug, 12-point fuel injectors, a generator with a segment conductor or a planetary reducer, and an electrical variable valve timing system driven by the engine. A subsidiary of Denso even created the QR code.

Denso's product range is quite diverse and covers many aspects of the automotive industry. These include components for Common Rail fuel systems, diesel pumps, sensors and valves, spark and glow plugs, ignition coils, parts for air conditioning and engine cooling systems, fuel and cabin filters, starters and generators, as well as windshield wipers. The company's products are available for passenger and commercial vehicles, buses, and other transportation vehicles.

Denso continues to be an important player in the automotive industry, focusing on innovation, quality, and global development.
