Clear Filter
Size: (Pack of 1)
Vehicle: 2020 Honda Accord LX 1.5T CVT 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.

Perfect fit, installed easily and quickly, airflow arrow was provided, and product was well-made with high-quality materials. Box had a hole, but the filter was in a sealed plastic bag and was undamaged.
