K&N Air Filters for Mercedes M112 V6 C320 E320 CLK320 C240 - Set of 2

Your M112 takes two air filters, and this listing is the matched pair — K&N 33-2181, the washable cotton-gauze element that replaces the disposable paper filter in both factory airboxes.
On a C 320 or E 320 that is now twenty years old, the airbox is usually the least-touched corner of the engine bay. A K&N is the cheapest honest improvement left on the platform: it flows better than a tired paper element, and you wash it instead of rebuying it.

Note on the photos: 33-2181 is a single long-running K&N part shared across the M112, M113, M272 and M273 engine families, so the images here show the same physical filter you will see on our other platform listings. That is the part, not a stock placeholder. If your Mercedes runs a different engine, we list this filter under that platform too — or send us your VIN and we will point you to the right one.
