HFC4GB1-3D 1.3L Bare Engine / Long Block – JAC Replacement Engine

This HFC4GB1-3D bare engine is a complete long block assembly built to OEM specifications for JAC vehicles. It is a 1.3L four-cylinder petrol engine from the JAC 4GB engine family, developed in-house by JAC with technical support from international engineering partners. The block, head, crank, pistons, cam and valves are all in place, and the assembly is ready to accept your existing intake, exhaust and accessories. This engine powered the Refine S2 Mini, Heyue A13, J3 and several other JAC compact models from 2013 onward, and it is still one of the most common engines in the aftermarket for these vehicles.
