# 858502 Muffler | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta silencer weighing 0.227 kg and listed for 3 applications. It supersedes 840943, which was catalogued in Swedish as an insugningsdampare - an intake silencer - so despite sitting in the Inlet and Exhaust System group this is an induction side part rather than an exhaust muffler. Worth confirming against the engine's parts list before ordering.
