DESCRIPTION
The Engine Piston Kit (Part Number: 4089843) is a set of components that make up the piston assembly in an internal combustion engine. The kit typically includes the piston, piston rings, wrist pin, and circlips. The piston is the heart of the engine and is responsible for converting the energy generated by fuel combustion into mechanical motion. The rings seal the gap between the piston and cylinder wall to prevent combustion gases from escaping and oil from entering the combustion chamber. The wrist pin connects the piston to the connecting rod, allowing for reciprocating motion. The circlips hold everything together in place. A high-quality piston kit can improve engine performance, increase efficiency, and prolong engine life by reducing wear on critical components.
