  • Don’t waste your money on OEM filters Don’t waste your money on OEM filters
I have not noticed much of a difference between OEM and K&N however I’m more than sure that the benefits of better airflow and reliability are certainly there. I have noticed a slightly better noise like a whistle noise when I rev my stage 2 N55! The readability how you can wash it honestly makes this better then the oem filter just with that feature alone! ... show more

  • perfect fitment, easy install, better airflow
I've been using K&N filters forever, great airflow and very good filtration. good for the life of the vehicle, just clean it every once and a while, reoil and you're good to go. well worth the money. also worth noting, it gave me better throttle response on my BMW 535i

Absolutely the biggest hp increase over what seems to be not a big deal.

  • Great Value
This item fit perfect for my ‘17 BMW X5. It is very simple to install and in my opinion a much better option than the cold air intake set up because this filter still uses the factory air ducts to pull in fresh outside air.
