Over time, we have found that the UNI filter that is used on the Alta R53/R52 intakes may deteriorate especially the collar where it mounts to the metal tube. If that has happened or you just want a fresh filter to work with here they are.

The Alta Performance™ dual stage, “Open Cell” foam cone Filter is the answer. Increases in horsepower are a simple easy install away! Quick cleans are simple with our aerosol cleaner and spray oil. Direct replacement for ALTA Performance intakes systems for Mini vehicles. Please check the Inlet Inside Diameter (I.D.) of the filter you need or are replacing as there have been a couple variations of intake design. This filter has a 2.75" I.D. Inlet. This filter comes in black only, red has been discontinued.

These are designed to fit the Alta brand (and may fit other brands) of intakes.
