BMW Intake Manifold Swirl Flap Delete Kit 32mm – M57 M57N2 M57TU M57TU2 Diesel

BMW 32mm Swirl Flap Kit for M57, M57TU and M57TU2 Diesel Engines OEM  – 11 61 8 519 140

This BMW 32mm intake manifold swirl flap kit includes 6 swirl flaps and gaskets for selected BMW 6-cylinder diesel engines equipped with 32mm factory intake manifold swirl flaps. It is designed as a direct replacement for worn or damaged factory-installed swirl flaps in compatible M57, M57TU and M57TU2 engine applications.

Swirl flaps are installed inside the intake manifold and help manage air movement under different operating conditions. Over time, factory swirl flaps may loosen, wear or fail, creating a risk of poor intake system operation or potential engine damage if a damaged flap detaches.

What This Part Does

Swirl flaps are intake manifold components used to control air movement inside the intake tract. In compatible BMW diesel engines, they help influence airflow and mixture formation depending on engine load and operating conditions.

This replacement kit is intended to restore the mechanical integrity of the swirl flap system during intake manifold service. Replacing worn or damaged swirl flaps can help reduce the risk of flap-related failure and support stable intake system operation.
