HKS PISTON RING SET T1 - 21005-AT001

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Piston rings are designed to seal the combustion chamber of your engine so that gasses do not enter the crankcase and oil does not enter the combustion chamber. If your engine is burning oil, losing compression, or if you are rebuilding your engine, it is recommended that you replace your piston rings.

In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.

Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Mr.Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name "HKS "), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan.

A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.

HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
