BMW 22mm Swirl Flap Delete Plug Kit for M57 Diesel Engines
This BMW 22mm swirl flap delete plug kit includes 6 plugs for selected BMW diesel intake manifolds equipped with 22mm factory swirl flaps. It is designed for compatible M57 engine family applications where the original swirl flaps are removed and the intake manifold openings must be sealed.
Factory swirl flaps can wear, rattle or fail over time. When the swirl flap shaft or dampers become worn, many owners remove the factory mechanism and install blanking plugs to reduce the risk of swirl flap-related intake or engine damage.

What This Part Does
Swirl flaps are installed inside the intake manifold and help influence airflow in the intake tract. With mileage, soot, oil residue and vibration can cause the swirl flap shaft or dampers to wear, creating rattling, air leakage or risk of mechanical failure.
This kit is used after removing the original swirl flap mechanism. The 22mm plugs seal the openings in the intake manifold and help maintain proper intake system sealing. It is a targeted repair kit for the existing manifold, not a complete intake manifold assembly.

FAQ
What does this BMW 22mm swirl flap delete kit fit?
This kit is listed for selected BMW diesel vehicles with compatible M57 engine family applications using 22mm intake manifold swirl flaps. Fitment must be confirmed by checking the original swirl flap diameter and manifold design.
Is this 22mm kit the same as a 32mm BMW swirl flap kit?
No. This product is the 22mm version. Production year up to 2004. 2004 was a transitional year (both 22mm and 32mm may be found). It should not be used on BMW intake manifolds that require 32mm swirl flap plugs. Always measure or verify the original swirl flap size before ordering.
What does this swirl flap delete plug kit do?
The kit is used after removing the factory swirl flap mechanism. The 22mm plugs seal the intake manifold openings and help maintain proper intake system sealing.
What symptoms indicate BMW swirl flap problems?
Common signs include rattling from the intake manifold area, reduced pulling power, worn swirl flap shaft components, loose flaps or concern about broken swirl flaps entering the engine.
Is this a complete intake manifold or replacement swirl flap set?
No. This product is a 6-piece 22mm swirl flap delete plug kit. It is not a complete intake manifold and it is not a set of working replacement swirl flaps.
How do I confirm compatibility before ordering?
Confirm your BMW engine family, intake manifold design and original swirl flap diameter. Order this kit only if your manifold uses 22mm swirl flaps; use a different kit for 32mm applications.
