Aisan Industry Kentucky, LLC is a consolidated manufacturing subsidiary of Aisan Industry Co., Ltd., a major Japanese automotive components supplier headquartered in Obu, Aichi, Japan. The facility is located at 65 Clarence Drive in Mount Sterling, Kentucky, United States, and focuses on the manufacture and sale of automotive components, with its primary product being fuel pump modules.
The company originated from the September 2022 acquisition by Aisan Industry of Denso Corporation's fuel pump module business, which included full ownership of the Kentucky operations then known as Kyosan Denso Manufacturing Kentucky, LLC. It was renamed Aisan Industry Kentucky, LLC effective April 1, 2023, to unify branding across the Aisan Group. The plant employs approximately 650 people and continues operations in the Woodland Industrial Park.
As part of Aisan Group's Americas network, it operates alongside other U.S. facilities such as Franklin Precision Industry Inc. in Franklin, Kentucky, and contributes to the parent's global supply of engine system components including fuel pumps, throttle bodies, EGR valves, and canisters. Aisan Industry Co., Ltd. is a leading supplier to major automakers, particularly Toyota (a significant shareholder), and holds a substantial position in the fuel pump module market with approximately 40% global share following the Denso integration.
In June 2026, the subsidiary adopted Celanese Corporation's POM ECO-C polyacetal resin, produced from captured CO2, for fuel pump modules supplied to a North American automaker. This reflects ongoing efforts in sustainable materials while maintaining performance standards in automotive applications.
