K&N Drop-In Filter R50 MINI

We like the K&N drop-in filter because it's affordable and it works. The K&N drop-in panel filter for MINI fits right in your factory airbox, but is made of pleated fabric instead of paper, which means higher airflow AND excellent filtration. It's backed by K&N's famous Million Mile warranty.

Available for most 2002-2006 Mini Cooper.

Please be careful about which filter you need. Filter A is for manual transmission Coopers from August 2004 through 2006 build dates. Filter A is TRIANGULAR. Filter B is for ALL Cooper (non-S) automatics from 2002-06, plus convertibles through 2008 model year. Filter B is RECTANGULAR. If you are in doubt, please check under your hood and make sure your filter shape matches!
