Fits perfect in '09 SLK 350
Fits perfect in my 2009 SLK 350 perfectly. It was a pain in the rump to install due to location, but after I saw how bad my old one looked, I'm glad I bought this!

Works the same as OEM but way cheaper. The only issue is MB hasn't caught on like other mfgs to design the HVAC system for easy cabin filter replacement. I can change my Tundra cabin filter in 5 seconds. This on my SLK not so much.

The exact replacement part with very good installation instructions
The Mann-Filter CUK 3621 was the precise replacement for the cabin filter on my '09 SLK 350. The installation instructions were most helpful since this filter is buried up under the dash above the passenger footwell. I would highly recommend this manufacturer and product for all of my fellow Sportlich (sporty), Leicht (light) and Kurz enthusiasts.

Quick shipping and good quality product.
Shipping was quick! Product quality is very good however, the instructions was inadequate otherwise I would have given this a 5 star. Now that I know how to replace it (should be easier the second time around), I'll order the same product when replacement is required.
