Alta R56 Drop In Replacement Air Filter Mini Cooper S 07+

The ALTA panel filter is not just a normal panel filter replacement like many others. The older R53 Mini air box was made pretty well in that the portion above and below the filter is very open. The New R56 filter is much different! The lower portion of the R56 filter has very little room for air to travel across the entire filter. We saw room for improvement in this filter by making it slightly offset and slightly thinner. This simple change allows for more air to be drawn across the entire filter. Besides that, it is a high flow foam filter, which like all our other filters provides less restriction, and the ability to clean it for the life of the car. From the diagram below you can see how much thicker the OEM filter is and how far it hangs down. The Alta filter provides roughly 2 times the volume of air under the filter. Dyno results will follow very soon! Installation of this filter can be done in 5 minutes of work and be clean hundreds of times before needing replacment.
