It all started in 1946. Tony and Wilfred, with the help of their father William “Pops” Neltner, opened a filling station in Newport, Kentucky. The Neltner’s believed customer service would set the family filling station apart from all others. They not only believed it, they demanded nothing less than the very best from themselves and their employees. With this mindset, the company became successful.

In 1953, an opportunity arose to purchase Kentucky Motor Service located down the road in the city next to Newport, Covington, Kentucky. With the purchase, the focus of the Neltner's and the business began to change to auto parts.

Continuing with their strong work ethic and dedicated customer service, the business grew with its success. Over the next several decades many locations and businesses were added and acquired throughout Kentucky, Ohio, and Indiana...hence the name KOI. Included with Kentucky Motor Service came more acquisitions including familiar names you still hear today like Wilcox Auto Parts, Savage Auto Parts, and more. All encompassed under the KOI Auto Parts name.

In 1987 KOI become a member of the Federated Auto Parts group giving KOI access to even more competitive tools and programs to offer its customers.

Generations later, the operating principles and focus on customer service which helped start the business remains the hallmark and competitive advantage of KOI Auto Parts today.
