Verify dimensions of your car's cabin air filter prior to buying - Although Amazon says it fits, it doesn't fit a 2006 BMW 330Ci

I failed to know all I needed to know prior to buying this cabin air filter from Amazon - As a result I didn't know that Amazon's on-line website tool was wrong when it identified this Mann CUK 8430 Cabin air filter as the one for a 2006 BMW 330Ci.  This CUK 8430 filter does not fit that application.  My 2006 BMW 330Ci's cabin air filter is 50% smaller than this Mann CUK 8430 filter.

After the new filter was received and the error was realized, I checked the Mann website.  The Mann filter website also incorrectly identifies the CUK-8430 filter for the 2006 BMW 330Ci application.  I would imagine the Amazon fitment info is plagiarized from Mann.

Even with this mis-information from Amazon and Mann, if I had done my homework prior to ordering the part, I would have realized the replacement part (rectangular) didn't match the original (curved) filter.  My failure to do the simple job of removing a cover and looking at the original filter prior to ordering the new filter results in time wasted returning this incorrect part and ordering another one.

Know what you need before you buy a part - especially if it's the first time you're buying it.  Don't depend on someone else to do your homework for you.

I became much smarter tonight - I now know that the cabin air filter that fits in my 2006 BMW 330Ci is the Mann CUK 6724.  The Mann website and Amazon both call out this CUK 6724 filter for a 2005 BMW 330Ci.  Amazon provides a photo and the Mann website provides detailed filter dimensions for the CUK 6724.  Armed with this information, I know that the CUK 6724 matches the filter in my 2006 BMW.  I'll be ordering that Mann filter tomorrow, once I return the wrong filter.

The website is misleading. It said the pad is fit to my 2008 BMW 535i, however, it is much smaller than the one on my car. It's not fit!
The vendor (Autocare Depot) tried to deduct 20% of my refund and only to gave me full refund at courtesy (original statement) after I showed the evidence (ironically, it still claims it's fit to 2008 BMW 535i today). The vendor claimed the compatibility tool is Amazon's and has nothing to do with them. My question is that as a retailer, should you make sure the information on the website is correct?

Item does not fit 2011 BMW X5 35i as stated by Amazon. Stick to the Mann filters and stay clear of this item.

Said fitment was correct, but this sensor is about a foot too short for the 2001 330ci.  Waste of my cash.

It advertises for a Honda Accord 4DR Sedan, which it is, but only for 4cil. not a 6cil. i know a should of payed more attention but i was so happy to find what i was looking for, that i did not notice that the cut out for the left exhaust was not there. (6cil have  double  exhaust) But in my defense the add should specify that it is for only 4cil Honda Accords and not for six. other then that, it was a perfect fit. I only had to cut the left side for the exhaust.

Bought this filter for my 2004 Lexus ES330 due to reviews. When I went to put it on the car, I realized it required a different size filter wrench (cap) than the Lexus oil filter. Fortunately I had a Lexus filter on hand so I put it on. In order to use this filter, I have to find the proper size filter cap for it.  I will try to use it next oil change which will be in a year or so.

Would not fit car like Amazon said it would.

i guess i should have measured my AC unit more carefully, because this cover seems big enough to cover a Volkswagen!  Be sure to measure accurately before ordering!

I needed a cabin filter for my 2010 Honda Fit.  That' what I entered into the Amazon Search Engine and this item came up.  I ordered it and when it arrived, I found that it is for Honda Fits previous to that model year.  When I contacted the company, they informed me that I would need to send it back to get a refund.  Not worth the time or expense.

Do NOT buy this combo. Engine filter is fine and a breeze to install, hence the 2 stars. Cabin filter, however, does NOT fit. It is way too think and cannot be inserted all the way into the housing. Look at the images yourself. 29 folds for the original and whopping 46 for the replacement. To install, you have to squeeze the filter first and then it'll go in easily, I just reinstalled the original this way, but the replacement will not go in. Now I have to buy another cabin filter.

This review is not based on the function of the filter, but just the fact that it is not necessarily compatible with all models of Volvos.  I was looking for a cabin air filter to fit my Volvo S80.  Even though this filter states it wil fit, and even the instructions that were included state the same, it will only fit in the larger slot of the cabin air filter (1 1/2" thick; closer to the engine), and not the smaller slot (1" thick, closer to the cabin), which was what I was lookng for.  Unfortunately, this was not stated in the item description, so be aware before buying.

So I have a spare filter I'm stuck with since I threw out the box.  But as far as filters go, construction looks solid, and I'm sure it would have worked well if I was able to install it.

Hey this didn't fit my car but I passed the return date on Amazon, can I still return it and buy a different one?

There is a real problem with these cars finding a radiator fan that fits.  Apparently there are two radiators for the Acura Integra and this fan did not fit mine.  It's unfortunate they don't provide a diagram with measurements.  then you could verify the fit before you order it.

Their fitting is for a very very small car.  It's supposed to fit regular size but it didn't fit my 2005 Mercedes C230 sedan, which is small sedan.  Also, I've returned the product but they haven't credited me back yet. I sent it back to them over 3 weeks ago.

This item, Mann Filter C2851 is a couple of inches too long for the filter housing in the 2006 Mini Base Model.  The car model checker at the top of the page seems to think it is the correct fit though.

Only 1 star due to advertising the incorrect model - the item itself seemed very well made if it had fit.

Misleading fitting guide.  Amazon states it fits a Subaru 2010, but it does not.  I ended up cutting out the paper filter element from both the replacment and oem filter and swapping them and glueing it back.  Should have researched more as other sites say the 3690 only fits Foresters up to 2008.  So do not get if you are 2009 +.
