Piston Ring Set - 12033AB640

Piston rings play a crucial role in your vehicle's engine, primarily responsible for sealing the combustion chamber. This prevents the combustion gases from escaping, maintaining engine efficiency and power while also regulating oil consumption. Without a properly functioning piston ring set, your engine's performance would significantly decline, resulting in power loss and increased emissions.

The piston ring set fits snugly around the piston within the engine. It consists of multiple rings that each serve a particular function – sealing the combustion chamber, controlling oil lubrication, and transferring heat from the piston to the cylinder wall. Together, these rings ensure optimal engine operation through reduced friction and proper oil ion levels.
