Improve the reliability of your BMW diesel engine with our N47 / N47S Swirl Flap Delete Kit, designed to eliminate the risk of failure associated with the factory swirl flap mechanism.

The kit includes a precision-machined billet aluminium swirl flap motor blanking plug, along with a premium set of four intake manifold gaskets, providing the essential components for a secure and reliable installation.

Designed for compatible BMW N47 and N47S diesel engines, this kit is an ideal preventative maintenance upgrade, particularly for higher-mileage vehicles.

What's Included

  • 1 x Billet Aluminium Swirl Flap Motor Blanking Plug – Precision-machined for a secure fit.
  • 4 x Intake Manifold Gaskets – High-quality replacement gaskets for reliable sealing during reassembly.

Why Delete the Swirl Flaps?

BMW's N47 diesel engines use swirl flaps within the intake manifold to help control airflow and improve combustion under certain operating conditions.

Over time, repeated heating and cooling cycles, general wear and carbon build-up can contribute to deterioration of the swirl flap mechanism.

If components become loose or break, there is a risk of debris entering the engine, potentially causing serious internal damage and expensive repairs.

Removing the swirl flap mechanism eliminates this particular mechanical failure risk, making it a popular preventative maintenance modification for compatible BMW diesel engines.
