MANN-FILTER CUK 6724 Activated Carbon Cabin Air Filter
Musty smell from the vents, weak A/C airflow, or exhaust odors getting into the cabin in traffic? The cabin filter is the usual culprit — and on E46-generation BMWs it is a single long element that is quick to replace.
The MANN-FILTER CUK 6724 is the activated-carbon version (CUK = carbon; the plain CU 6724 is particulate-only). Besides trapping dust and pollen, the treated activated-carbon layer adsorbs harmful gases such as ozone, nitrogen oxides and sulfur dioxide, and keeps street odors out of the cabin.

What is the difference between CUK 6724 and CU 6724?
CUK has the activated-carbon layer (odor/gas protection); CU is the plain particulate version.
