Engine Family Overview:
With nine models ranging from 4.3- to 14-horsepower, the Subaru Overhead Cam Industrial Engines lead the industry in technology, offering more power, less noise and easy, one-pull starting every time. Introduced as the first air-cooled engine line to use advanced chain-driven Overhead Cam technology, the Subaru EX Series provides maximum efficiency, performance and power with minimal noise and emissions. The engine design is extremely compatible and easy to install, and simply exchanges with most existing slant cylinder engines.

In the recreational arena, you’ll find EX industrial engines in go-karts, while the home and garden user will find Subaru powering tillers, edgers, reel mowers and blower/vacs.
