## 🔌 Function

Damps pressure pulsation and induction noise in the intake path without choking the airflow the turbocharger needs.

## ⚠️ Common Signs of Failure

-   Harder induction roar or intake noise that was not there before
-   Absorbent lining broken up, shedding, or drawn towards the turbocharger
-   Casing split, crushed or distorted at the joints
-   Loose fit at the air-cleaner connection, whistling or drawing unfiltered air

## 🛠️ Service Notes

-   It supersedes 21353976, which was listed as a cap, so a search on the old number may not look like the same part
-   Check the air-cleaner assembly and the intake ducting for loose material whenever a sound trap has broken down, since anything shed goes straight to the turbocharger
