Permanent filter
Love the permanent air filter for my 2025 Toyota Tacoma. Easy install and much more effective than the paper filter.

High quality reusable air filter!
Another high quality K&N part. Fit my 24 grand Highlander as expected. I enjoy the reusability of these filters as well as the increased performance.

Better filter not performance
2023 Camry XSE. New filter to replace my OEM filter. Did research to see was it worth the upgrade. On dyno, Carquest filter slightly out performed OEM filter (1.4%). On dyno, K&N filter out performed OEM by 3.5%. K&N filter is longer lasting, and I'm willing to clean it. I didn't get the cold intake because the engine area doesn't breathe well enough. The filter was very easy to put in. No tools needed. Took 5 minutes tops. Fit great. Dropped right in.
