Subaru Industrial Power Products’ SP Series engines offer advanced overhead cam technology for heightened performance and the industry’s lowest total cost of ownership. Designed for the light commercial and premium residential engine markets, SP engines provide more power and easier starts, while minimizing noise and emissions, making them ideal for use with pressure washers, generators, pumps, go-carts and a variety of lawn and garden equipment.
Utilizing a high-performance automotive design, SP Series engines feature chain-driven OHC technology combined with an efficient hemispherical combustion chamber for optimum engine performance. Intake and exhaust valves are positioned to lower resistance for the air/fuel mixture, while a high compression ratio produces greater power and torque.
Ranging from 5.7- to 7-horsepower, Subaru’s SP Engines comply with EPA emissions regulations and are backed by Subaru’s 3-year limited warranty.
