HKS is one of the founding pioneers in the Japanese Aftermarket Tuning industry. They have provided quality products that have been extensively researched, tested, and employed throughout many powerful vehicles for enthusiasts worldwide. HKS was founded in 1973 and named after the founders Hasegawa, Kitagawa, and Sigma. More importantly, some of the first aftermarket turbochargers were designed and developed by Mr. Hasewaga which led to the birth of some of the most innovative products that has made the love of upgrading possible today. In may ways, if it were not for HKS our industry would not be what it is today.
