HKS specializes in aftermarket high performance auto parts engineering and manufacturing, and perhaps is the most known aftermarket brand in the world. Formed in 1973, and named after the founders Hasegawa, Kitagawa, and Sigma, HKS began tuning engines and cars with a vision to tune and manufacture high performance engine components and turbo kits that surpasses OE Manufacturers.
JDM Design, OEM Fitment
