3801911 Turbocharger Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured turbocharger from the Inlet and Exhaust System group, weighing 39.80 kg and listed for one application in the TWD series. It is a large unit - well clear of the 25.56 kg TWD turbocharger 3801910 - so the published weight is a genuine cross-check here. This unit is supplied on an exchange basis: core deposit 3804911 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
