Smoke and fluttery/uneven idle when starting up, "misfire" or engine rocking. Rough running even under a light load, lack of power, boost leak from manifold, engine ‘hunting’.

The swirl flaps within the intake manifold become covered in carbon deposits restricting air flow and can fail.

BMW introduced swirl flaps into all of their diesel engines from 1998. The swirl flaps are designed to close at lower speeds to improve torque and then to open at higher revs for an improved fuel to air ratio.

However, over the years soot builds up on these moving parts and within the intake ports. Images can be seen across the internet showing these manifolds completed coked up with carbon deposits, putting excess stress on the swirl flap components.

Not only does this restrict air flow and performance in some instances it has led to failure of the swirl flap components and these parts entering the engine.

Remove the swirl flaps and seal with our kit, improve air flow and prevent any future issues.

Remove the swirl flaps and never worry about your engines swirl flaps ever again!

Our part is designed to block the hole created by the removal of the swirl flaps. Please check out our instructions and video showing this process.

Our unique bung with its double Viton seal (Viton is the correct material to use here to prevent future issues, check what you buy) perfectly seals the manifold after removing the swirl flaps stopping any boost leaks.

The swirl flap actuating motor is left connected and running as normal so will not trigger any fault codes. Removal of these parts does not affect vehicle performance and in some instances performance is improved as these components (and lumps of carbon build up attached thereto) are removed.

Our kit also comes with a rubber viton spacer. This is essential as in some instances a small piece of plastic is missing from the actuator motor. If this is missing, without this spacer the bung will not work. Please check you will receive this if buying elsewhere and that it is Viton, many don’t understand what they are selling.
