CISON L4-175 17.5cc Mini OHV Inline 4 Cylinder 4 Stroke Water-cooled L4 RC Gasoline Engine Model - Speed Up to 8,000rpm

In 2022, we launched the CISON FL4-175 flathead L4 gasoline engine, and now we present its upgraded version - the L4-175 OHV L4 gasoline engine. It maintains a unique, mini and compact design with similar displacement to its predecessor. The new CISON OHV L4 engine features red sports elements, a roughened crankshaft, and a bionic carburetor. Its OHV valve mechanism provides better power output and torque performance than the flathead engine, making it ideal for RC off-road trucks and towing vehicles. This engine comes with standard electrical starting, a water cooling system, and an independent lubrication system. Customers can choose from two versions: KIT or assembled. The CISON OHV L4 engine is now available for purchase. For any questions or advice, please contact us at
