    • Fit perfectly in 2021 Rav 4 - you won't be disappointed
Pros: Fit perfectly in a 2021 Rav4, as others say. Seem to be good quality. Good price. Saves $50 labor cost by putting these in yourself. Cons: Can't think of any, honestly.

    • Fits 2021 SE Camry 2.5L
Fits my 2021 Camry 2.5l SE. No difficulty on the fit in the box. Box fit right on and two clamps were easy to fasten. I will be buying these from here on out every year 18k. Don’t expect the dealerships to change them during your 2 year free maintenance or regularly. Mine did not. Only issue I had was I didn’t get a brand new unopened filter. It was a return, but I didn’t pay for a used/returned one. It was still in like new condition and not damaged. I expect the person ordered wrong one and returned. I’m leaving five stars on the quality and eases of fit of the filter. Good job K&N. It matches or exceeds OEM. ... show more

    • Quality Filter K&N always Premium
Build is great and K&N has good reputation. Filter was in box with no poly bag over it. I initially thought this was returned item but all was brand new no stains. So I kept it. It had translucent holding filter pleats together in shape which was nice to have. Other than this it fit perfectly.

    • This is a high quality fifter.
I replaced my inside cabin air filter on a 2016 Toyota Highlander. This filter was a perfect fit. And it was a better quality than the filter that came in the vehicle. Couldn't be more pleased.

    • Time and money saver
Perfect replacement for my car and had very little issue installing. Bought this and my cabin air filters together and spent far less than what the dealership wanted to charge me for the same work. Definitely worth it in the time and money saved. Will definitely be buying again the next time.
