 Development possible because of true "In-house" production

When HKS refer to "in-house", it does not simply mean to produce everything with our own facilities. HKS does build from the ground up instead of looking for a guide from the vehicle manufacturers. The design, processing, test and production are all linked together with particular attention, therefore, the testing and redesigns are based on those results. The results of this R&D are then reflected in the final production of the items. All of this is necessary to provide the customer with a product which they can be truly feel happy with and to maintain HKS' position as the pioneer in the tuning industry From

"Bolt-on" to Full Tune-up Specifications.
