Quiet strength

The high performance of the EX Series engines from Subaru are powered by chain-driven overhead cam technology, running between 4.5 and 9 hp. Engine noise is reduced through fewer moving parts and optimized-capacity rigid mufflers. Several sets of heat dissipation fins, combined with 360-degree airflow around the exhaust and intake valve stems, regulate temperature to avoid engine failure. The patent-pending oil delivery system keeps the engine running smoothly without spouting.
