A great package with the replacement filter for the JCW Intake and the MOTORING Book.
If you have the optional John Cooper Works air intake then you've got some work to do. 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. Gain 4-5 horsepower with only about five minutes work.
