The K&N 57i induction kit for BMW Mini One/Cooper 1.6L (16V) replaces the factory air box with a larger washable, reusable filter and tailored adapters to improve airflow and support power across the rev range. The increased filter surface reduces restriction and extends service intervals before cleaning; the kit is backed by K&N's No-Hassle Lifetime Limited Warranty and may be restricted in some emissions-controlled states.
