HKS put all our know-how knowledge into our ENGINE parts from the data we have acquired from the drag race, round race, time attack, drift race and etc.

What in-house production can do.

HKS stick to in-house production for engine parts. It’s just making the parts from 1 to 10. And we don’t just make parts from the stock parts but we design from 0. We design from scratch and test and resign and test and so on for the best result. This how we make the best products for aftermarket from the 40 years ago. As a pioneer of the aftermarket maker we know how to satisfy our customers.
