Fits perfect and works as designed. Flows like OEM and looks well made.
Style: BE-553B 1-Pack
This filter is very comparable to the stock filter. Fits the BMW G20 just like OEM. I would not say it is two times "heavier" as advertised on the box, but it is very comparable to stock. It's the same weight and similar construction. BMW has a very robust cabin filter. This will be my go to. I did purchase another aftermarket cabin filter that fit well, but was thin, flimsy and had a bad chemical odor. This one is fine and airflow is the same as OEM. I change them every year or so. I don't worry too much about longevity with cabin filters personally.

Good quality but it was slightly longer than original and needed modification.
Style: BE-182 1-Pack
Bought this cabin filter for a 2023 Acura TLX. While the filter seems to be made of quality material, it was just a little too long (about a 1/16 of an inch, so I had to trim it to make it fit so the cover would fit snug. I was able to do that without compromising the filter itself. But this might be an issue for some people

Fits my Chevy 2021 Bolt Premier perfectly.
Style: BE-966 1-Pack
Installation was a breeze, fir nicely and the air in teh car now smells fresh and clean. The old filter has developed a musty smell so this new one is great. Had it replaced in under 3 minutes.

Fits perfectly for my 2017 VW Passat
Style: BE-373 1-Pack, Style: BE-373 1-Pack
Bought this for a fraction of the cost. An auto shop wanted to charge me $72.99 for a filter so I bought this Spearhead brand cabin filter and its the perfect size and its just as sturdy as the previous one the dealership had in the car. Not sure yet how the airflow is or if anything different as I have not driven in the car since it was replaced, but it appears to be a very high quality cabin filter for my car at a great price.

Good Quality Replacement for Lexus
Style: BE-285 1-Pack
Was a perfect fit for my 2016 Lexus NX200t. No tools required. Total of 5 minutes to install. Airflow is good after replacement and the activated charcoal seems to make a difference in reducing any smells from outside. Recommended.
