WAI Global is an international brand specializing in electrical and electronic replacement parts for automobiles, with a particular focus on starters, alternators, ignition components, and sensors. Founded in 1978, the company began by supplying spare parts for American vehicles. Its catalog quickly expanded to include Japanese, Korean, and European models, making WAI a significant player in the global aftermarket.

Between 2000 and 2015, WAI continued its expansion by opening subsidiaries in the United States, China, Europe, and South America. This international growth allowed for a broad product range and a rapid launch of new parts on the market. In 2016, WAI was acquired by DENSO Corporation, a major supplier in the automotive industry. This acquisition provided access to advanced technologies and global distribution networks while allowing the brand to maintain its independence in the aftermarket sector.

Looking ahead, WAI focuses on vehicle electrification by developing new components such as charging modules for electric vehicles (EV), battery management systems, and high-voltage components. Additionally, the company continues to invest in sustainable remanufacturing programs, where used starters and alternators are carefully inspected and reused. WAI is also expanding its catalog to include parts for cooling, lighting, and comfort systems. Digital support through online catalogs and technical tools helps workshops and distributors quickly and accurately find the right part.
