High performance and reusable
Excellent quality air filter. It provides a high performance long term to your car and it is reusable. You only need to washer with degreaser or the care kit from the same brand that sells separately. Very easy to install as well.

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.
