Great price
I love Mann filters. Great for the price and great quality. I was surprised how cheap they were ( my car takes 2 filters and two come in the box). They fit like a glove and now I am enjoying fresh air

Can’t beat MANN quality
Bought to replace the filters on my 2015 bmw x5 as there was a musty smell from ac. Old filters were another junk company that fit very loosely. I was impressed by the quality and how secure the MANN filters locked into the housing; musty smell all gone now! Easy 10min replacement job, comes with VERY detailed instructions for the less mechanically inclined

Great product
Fits our 2012 X5d perfectly. Do yourself a favor and youtube the process for replacing these. You'll see it's well worth doing yourself rather than paying a shop that charges a BMW premium on everything.
Also something I learned recently... this is a low cost high charge item at the mechanic. A lot of times when they suggest replacing these it's because they just tick the box and don't actually look at them. We had our mechanic admit this on a recent service where it was suggested to replace, when we had just done it ourselves in April.
