List of products by brand HKS

HKS was formed in 1973 by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Goichi Kitagawa, while the start up capital was supplied by Sigma Automotive (hence the name HKS). The company began operations by tuning gasoline-powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan. Their goal was to design and build high performance engines and components that major original equipment manufacturers could not, or would not, produce. In July 1974, Hasegawa engineered and built the first commercialized turbocharger kit for passenger automobiles, since then developing turbocharger upgrades and bolt-on turbocharger kits that subsequently became the core business of HKS. Hasegawa also created the first commercially available electronic turbo timer and boost controller.

HKS is a publicly traded company with an international sales and distribution network spanning Asia, Europe, Australia and the Americas to support its customer base. The company remains near Mt. Fuji with its main manufacturing and R&D facility in Fujinomiya City, Shizuoka Prefecture. Subsidiary companies have been established in Cambridgeshire, England (HKS Europe), Bangkok, Thailand (HKS Thailand).

Motovicity Distribution was selected as the North American warehouse and in May 2020, Motovicity Distribution's assets were acquired by Turn 14 Distribution who currently handles authorized distribution of HKS's products in the United States.
