Genuine AGCO Piston Rings are the best choice for your engine. They provide consistent pressure on the cylinder liner, keeping combustion gases in the cylinder and providing correct oil film on the cylinder walls ensuring proper lubrication. Non genuine piston rings might seem identical to the naked eye but can have insufficient pressure leading to increased blow-by which causes power loss and increased fuel consumption or excessive pressure that removes the oil film and leads to increased rate of wear.
