STEMnex V8 Model Engine kit builds a realistic, though greatly simplified, working model of a combustion engine and includes light and sound features, light-up spark plugs, moving pistons, valve gear, fan belt, and all the parts and tools you need to assemble the working model.

Unlike other inferior models, the STEMnex V8 Model Engine uses no glue. Parts screw or clip together, so the engine can be taken apart and rebuilt multiple times. The informative manual gives clear, step-by-step instructions to guide your teen through the building process
