Upgrade your BMW 640d’s breathing with a K&N cotton gauze sports panel filter. Designed for the 3.0d N57 engine in the F06 Gran Coupe, F12 Convertible and F13 Coupe, this serviceable insert replaces the factory paper element and delivers freer airflow, crisp throttle response and a richer induction note while retaining excellent filtration for UK road conditions.
