ALTA Performance was the first to offer you a replacment high flow drop in filter for your R56 and JCW.  This enviromently responsible filter is completely reusable and will last you the life of your car!

High Flow Drop In

Our high flowing, super cleaning foam media allows us to make the filter thinner while keeping the maximum amount of volume to hold dirt.  This simple change allows for more air to be drawn across the entire filter.  This also allows for 2 times the volume in the OEM intake box, and allows for the intake to breathe that much better!

DYNO PROVEN HORSEPOWER

The ALTA Drop in filter makes a few extra HP but where it really shines is when it gets dirty.  OEM and K&N filters get clogged the more dirt gets in them and loose horsepower.  The ALTA Foam media keeps flowing even after its full of dirt providing you with maximum horsepower between filter servicing.

GO GREEN WITH OUR REUSABLE FILTER

Like all ALTA intakes systems, we use a special foam media which not only flows more air and cleans better than the stock filter, it is also reusable!   Our high flow foam filters are 100% reusable for the life of your car! This means you will never throw it away and add to your local land fills! 

EASY TO READ RED COLOR

Red colored foam is used to help indicate when its time to clean.   Who would have though so much engineering could go into such a simple part.
