Horsepower Inc

The shop is based out of Indianapolis and is a one stop shop for performance upgrades from start to finish. The machine shop manufactures their own product line in-house on state-of-the-art equipment from United States materials and United States labor. It all started in 2002 when HPi was the first company to manufacture an aftermarket throttle body and intake replacement for the Harley-Davidson® industry. A key advantage over competitors is the fact that HPi continues to react to changes in the fuel injection market before anyone else. They are one of the only companies to offer a throttle body for all makes and models of Harley-Davidson® motorcycles that fits all popular build specifications, while staying O.E.M. Over the years HPi has invested tremendously in new technology to expand their product line and produce quality products they are proud to stand behind. These performance products include, throttle bodies, air cleaners, hand-made exhaust systems, injectors, fuel rails, and much more. What they do not offer in-house, they can get from their performance industry partners they have built close, respected relationships with to produce quality combinations for any desired build.
