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

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.

The original, the best.
Works great like every other one I’ve bought in the past. Beats the cellulose-pleated overpriced filters out the water.

Fit's extremely well in replacement of the original filter. Was easy to remove air box lid so took about 3 minutes to do. (different vehicles and air box positions may vary this)
