DESCRIPTION
The Engine Piston Kit, with part number 4089461, is a set of components that work together to form the engine's combustion chamber. The kit typically includes one or more pistons, piston rings, and wrist pins. The piston is a cylindrical component that moves up and down within the engine cylinder, transferring energy from the expanding gases to the crankshaft. Piston rings help seal the combustion chamber and prevent oil from entering the combustion process. Wrist pins hold the piston in place and allow it to pivot as it moves up and down within the cylinder. A well-designed piston kit can help improve engine performance by increasing power output and reducing emissions.
