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. Our 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. Compare our pricing to another popular MINI vendor- save $39! Fits both R53 and R56 JCW Intake systems!

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!
