The issue is the origami paper filter that Mini puts in the JCW airbox:

- It is wildly expensive for a disposable filter - around US$100. While Mini will replace it as part of the included maintenance package, they will do so only after 30K miles, by which point it will be completely clogged.

- The paper element is very restrictive even when new, and makes the JCW intake much less of a performer than any of the aftermarket CAIs.

Here's a $40 solution that should be good for 3-5HP vs. the stock filter - a K&N gauze filter to replace it...
