To develop ENGINE parts HKS uses all the knowldedge acquired from drag race, road race and drifting.

What in-house production can do.

HKS follows the philosophy of in-house production for the engine parts. We are not simply making some parts, neither do we follow the ideas of stock car makers, in HKS we go through each and every step from designing to manufacturing to testing and mass production. Each product undergoes numerous cycles of test and redesigns to achieve outstanding performance and excellent quality. This is an indispensable part of our business philosophy, that we believe is essential for aftermarket parts maker. This is how we work for 40 years and this idea will continue to lie at the basis of how we enhance our products to fulfil the expectations of our customers.
