Not sure if there is a longevity issue with these but these are fair priced and fit perfectly in my 21’ accord sport and 20’ CRV-L. I will be buying this again next year

Clear Filter

The stealership wanted $60 in my area to change this out. Just look up online how easy it is to do it yourself. Can easily be handled in a minute. The only real thing to note is that it took almost a full gas tank for the car's computer to re-learn how to idle smoothly again. Of course, this is because it learns to compensate for the old dirty filter. So it has to get used to the new/fresh one. Overall, the look and feel of this product is great. Very similar to OEM. After the idle smoothed out it's virtually identical in performance. Would recommend to anyone.
