HKS Intake tuning technology gives users to have more power by reducing the air pressure for intake process. HKS Intake series are designed for each vehicle that these new vehicle has highly complicated computerized system, therefore we analyze the system make the what’s most efficient for engine to response best for the air it get at a safe level. It is not simple to improve performance just by decreasing intake friction. Even efficiency and performance are increased, if ECU or sensor are not properly set, engine might be damaged. Latest vehicles have complicated control system for emission control or improving fuel consumption. Small improper setting may damage engine after several months. Too much efficiency improvement should not be done! Development of HKS products are well balanced for efficiency and control.
