BMW 32mm Swirl Flap Kit for M57, M57TU and M57TU2 Diesel Engines
This BMW 32mm intake manifold swirl flap kit includes 6 swirl flaps 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.
