Depends on what your motivations are. I’m more utilitarian so I wouldn’t use one since, despite increased airflow, they’re said to have poorer filter capabilities than paper filters. There have also been problems with the oil on those filters screwing up MAF sensors. They’ll make a turbo sound way more audible and I’ve seen some people post that they’ve run K&Ns on so and so vehicles for more than a decade without a problem but I’ll take a good paper filter over it anyday.

Your mileage may vary. If you do some googling you’ll get a lot of results on that topic.

For better responses from others, it might help to post what car you intend to put it in and what you’re looking for. Is it the sound, potential horsepower gains, etc?

I know for a Chevrolet Cruze I wouldn’t consider it unless I was sure its filtration was just as good as the paper filter, but that’s just me (long-term reliability oriented). On the other hand, pearsonba350 on YouTube put one on his Cruze and he seems to love it.
