Description
If your Ski-Doo Formula Deluxe 500 is losing compression or showing signs of blow-by, a worn piston ring is likely the culprit—and it’ll tank your engine’s efficiency and throttle response. The Wossner 69.50 mm piston ring restores proper cylinder sealing, recovering lost power and fuel economy while protecting against further engine wear. This is maintenance-grade reliability that any serious snowmobile operator should keep on hand.
