Product Description Condition:100% Brand new and high quality. Material: Aluminum,Rubber OEM:11618507239, 11617801438

SYMPTOMS OF FAULT： 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 FAULT：

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

BMW introduced swirl flaps into all of their diesel engines in 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 completely coked up with carbon deposits, putting excess stress on the swirl flap components.

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

THE SOLUTION：

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

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 an aluminum 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.
