Honda K20A Engine
Lift the red cam cover to reveal the piston assembly in this Honda K20A-inspired engine model. The 907-piece build combines a compact four-cylinder block with bright silver intake and exhaust details, plus exposed pulleys and timing components at the front.
As the crankshaft turns, the connecting rods move the pistons through their cycle. Building these linked assemblies gives you a closer view of how the model converts rotation into up-and-down movement.

- Built dimensions: approximately 26 × 15 × 14 cm (L × W × H)
