Description Reviews Do you have the optional John Cooper Works air intake? When John Cooper Works created their MINI Cooper S airbox, they neglected to use a high flow performance air filter. Unfortunately, their JCW MINI Cooper S air box still uses a paper filter element, which is very restrictive, significantly limiting airflow. This replacement high flow velocity stack filter is a direct fit and installs in 5 minutes. The Amsoil replacement filter gives you both increased airflow and reusability at a very low price. Considering that the restrictive/non-reusable John Cooper Works replacement paper filter costs $170 to replace, can you afford not to make the switch? This Amsoil high flow filter can be cleaned so that it may be used for a very long time if properly maintained. Fits both R53 and R56 JCW Intake systems! Only fits the JCW intake.

I've owned oiled filters and just didn't want the added hassle that comes with cleaning and re-oiling oiled filters. The Amsoil filter is a snap to install, and I get a little more whine from the supercharger and a little more growl from the engine. Easy to maintain and better air flow, all at a competitive price. Thanks, Chad!
