829546 Piston | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta piston from the Lubricating and Oil System group, weighing 0.008 kg and listed for 4 applications across the MD series. At 0.008 kg this is a small oil-system piston rather than an engine piston, and the short fitment list means the engine designation should be checked before ordering.
