The K&N 57i induction kit for BMW 118D/120D 2.0D is an engineered intake solution that replaces the restrictive factory airbox with a larger washable, reusable K&N filter and adapter hardware to increase airflow and deliver power across the RPM range. It’s vehicle-specific and designed for straightforward installation. The larger filter offers lower restriction and extended service intervals, and the kit comes with connection adapters made from durable materials; note 57i kits are not legal in California and similar emissions states.
