Business Details

Full description and what we offer

HKS was founded in October 1973 by Hiroyuki Hasegawa (former Yamaha Motor engineer) and partner Kitagawa, with backing from Sigma Automotive Co., Ltd.—hence the "HKS" name. They began in a dairy-farming shed at the foot of Mount Fuji in Japan with a straightforward vision: design and build high-performance engines and components that OE manufacturers couldn't or wouldn't produce.

In their first year, Hasegawa designed and built the first aftermarket turbocharger for passenger cars. That innovation launched an entire product line that transformed the Japanese automotive aftermarket.

HKS designs and manufactures performance components across multiple categories:

Category	Examples
Turbochargers	GT turbine kits, full turbine assemblies, universal turbines (VR38DETT, FA24, 2JZ-GTE compatible)
Superchargers	Complete supercharger kits with installation support
Exhaust Systems	Hi-Power mufflers, LegaMax exhaust, HKStudie systems for BMW M3, Civic Type R, Tundra, GR Corolla
Suspension	HiperMax coilovers, oil cooler kits, complete suspension overhauls
Engine Parts	Complete engines, short blocks, timing belts, fuel management computers
Cooling Systems	Oil coolers, radiator kits, cooling line assemblies
Intake Systems	Intake manifolds, air filters, intake kits by vehicle
Blow-Off Valves	Electronic and mechanical boost relief systems
Aero Parts	Body kits, front bumper spoilers, side skirts
Electronics	Turbo timers, boost controllers, piggy-back fuel computers, F-CON powerwriters

"For over a quarter century HKS products have been put to the test in drag racing, road racing, rallying, and top speed trials."

HKS-equipped vehicles have captured numerous racing championships. Their European division focuses on Formula 3 engine development—competitors are racing and winning with HKS-prepared engines in today's F3 series. This "race on Sunday, sell on Monday" philosophy means street users get proven, competition-tested components.

HKS operates a state-of-the-art 100,000 sq ft manufacturing and research facility at the foot of Mount Fuji in Shizuoka, Japan. They're a publicly traded company with international distribution spanning Asia, Europe, Australia, and the Americas.
