Offered here is a used genuine OEM Porsche piston and connecting rod, part number 99610303111. Originally fitted to the 2.5L 2480cc H6 naturally aspirated engine in the Porsche Boxster, this assembly combines the piston and connecting rod as a single unit. Common failure symptoms include knocking sounds from the engine bay, loss of compression, or increased oil consumption when the piston or rod bearings wear. Also known simply as a piston or connecting rod, this component is critical for converting combustion pressure into rotational force.
