Arrow is AIRFLOW direction, not UP install direction
Arrow is AIRFLOW direction, not UP direction. So installation direction might mean arrow of your Purolator filter should be down (true for glove box installs) even if arrow on old filter is up (if it was an UP indication). I wish they mentioned this in product listing, on box, or on side of filter like most brands. Luckily, telephone customer service was super responsive. Otherwise, product is correct size, appears sturdily made.

Easy to install and great quality—perfect for my 2018 Civic
Size: 2.0L
I bought this for my 2018 Honda Civic, and it fits perfectly. It only takes a few minutes to install with just a few clips, and the process is simple. I am a woman and do it myself with no issues at all. The filter feels sturdy and well made. The thickness and overall quality are excellent. I’ve seen people mention “ease of cleaning,” but I don’t clean mine. I just remove, vacuum the area and replace it when needed. That might be a bit much, but it’s affordable and straightforward. I can’t say exactly how much it improves airflow or fuel mileage, but I consistently get over 40 miles per gallon in economy mode, so it’s clearly performing well. Overall, it’s a great product if you like handling basic car maintenance on your own.

Affordable and Reusable
Size: 2.0L
The engine filter was really affordable it cost less then $15. I bought this filter because it was recommended from a family friend. It fitted my honda civic perfectly. Replacing the filter was so easy to replace. Replacing or changing the filter was easy it only took a few mins to do. The quality of the filter is really good and it feels like its perfect for my car. I would buy this filter over and over again thats how great it is.
