BMW 4 Cylinder N47 / N47S Engine Aluminium Swirl Flap Delete Kit

Protect your BMW diesel from costly intake failures

The well-known weak point on BMW 2.0d four-cylinder units is the intake butterfly system inside the manifold. Over time these plastic components wear, loosen and can be drawn into the combustion chamber. Our precision alloy blanking solution replaces the moving parts with a solid, secure plug so you can enjoy peace of mind, clean airflow and long-term reliability.
