X4XZ Premium Cabin Air Filter with Activated Carbon for 2008-2020 Mercedes-BENZ AMG C230 C300 E350 GLK350 C350 CLS550 CUK29005

The problem with this Filter is the perimeter gasket is too thick creating a difficult and poor fit. If you compare this filter to the OEM Filter you will see this Filter is an inaccurate interpretation of the Mercedes OEM Filter.

Fits but a little hard to make the clamps connect.

this is a very fairly priced filter, and it works/fits perfectly. I will say, the longevity is a bit less... i get about a year out of them. i might just be overly cautious of it. this will fix the air pressure problem a lot of these older mercedes have. the pressure coming out of the vents after installing this was insane. I also love to put some air freshener or cologne on these, its a built in air freshener.

Is it this product or Mercedes...I'm not sure, but maybe some of both! I bought this cabin air filter for my 2012 E350. Let me start by saying I really don't work on cars, but from a YouTube video, this seemed pretty straightforward. Taking the old filter out was a piece of cake. Putting the new one in was a long and painful project. Getting the filter up where it belongs is pretty easy, except for the fact that it doesn't seem to slide in all the way. It takes a lot of pressure to try to hold the filter in place while trying to slide that white plastic slide (which holds the filter in place) to engage. I had to wedge a stick underneath to hold the filter in place while I tried..and failed.. to slide that little white slide over to hold the filter in place. It just wouldn't slide over to engage. After much sweat, I finally took the slide off and scraped some of the plastic from the bottom of the filter and the fins that hold the slide. Then, while prying the front of the U-channels of the slide open with a screwdriver, I heated them with a barbecue lighter to heat the plastic so it would stay open. I did this with all four U-channels. Yes, I do think the manufacturer of this product could make the U-channels wider, but maybe it was just my year/model Mercedes (though I think I read another review with the same issue). Then, I used a swab to dab some Vaseline into the U-channels to, hopefully, lubricate the whole thing. That finally worked! But then it was screwing the panel back in place, which Mercedes makes a lot more difficult than it needs to be. A better Torx tool than the filter seller provided would've been helpful here. Anyway, the reason for the three stars relates to the unexpected difficulty I experienced doing what looked like a really simple job. Some of the blame is on this product's manufacturer (make the U-channels wider or have a flared opening to them), some falls on Mercedes' shoulders for what seems like an unnecessarily cumbersome design (i.e. that white slide) and some falls on me for being too cheap to get the filter replaced the next time I bring the car in for service.

Fot perfectly in my CLS550....Installed in 15 minutes maybe...
