# 21039712 Air Duct | Genuine Volvo Penta Part

## 🔧 Product Description

Brand-new genuine Volvo Penta air duct formed for the original routing within the Volvo Penta TAD720GE engine air-intake system. Its bends, end connections and internal diameter preserve the designed flow path while avoiding interference, vibration and excessive stress on adjoining fittings.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD720GE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Engine air-intake duct for the TAD720GE installation
-   1.678 kg
-   Supersedes 20797133
-   Listed for one application

## 🔌 Function

Carries filtered air from the air cleaner into the engine, keeping the intake path sealed so nothing unfiltered gets in.

## ⚠️ Common Signs of Failure

-   Dust tracks or a clean streak inside the duct downstream of a split
-   Roaring or whistling from the intake
-   Air-filter indicator or boost readings drifting from normal
-   Duct found cracked at a bend or at a clamp shoulder
-   Clamp seals found perished so the duct can move on its spigot

## 🛠️ Service Notes

-   Any unfiltered air past a split goes straight into the engine - inspect the full length inside and out, not just the ends
-   Refit every clamp and support rubber; a duct that is free to move will crack again in the same place
