HKS
In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Goichi Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name “HKS ”), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan. A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.
HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
