This filter set for my 10th generation Honda Civic is an excellent value and fits perfectly. Before installing, I compared both the cabin and engine air filters to the originals to ensure proper sizing, and they matched exactly. Replacing the cabin air filter was very simple and straightforward. The engine air filter requires a bit more effort since you need to remove four screws to access the housing, but it is still an easy process. Once opened, you simply remove the old filter and place the new one inside. Both filters appear to be high quality and, in fact, looked better constructed than the ones I removed. I especially appreciate that this set includes both filters together, making it convenient to replace them at the same time. Recently, while at the dealership, I overheard a technician inform a customer that replacing her air filters would cost $90. Considering how simple the process is, that price felt excessive. This two pack is very reasonably priced, and I have paid nearly the same amount in the past for just one filter (not from the dealership but auto zone). These filters are well made, fit properly, and offer significant savings compared to dealership and ur local auto stores. I plan to continue purchasing this set for future replacements.

Compatible for 2018 Honda CR-V

This is a compatible fitment, as described in the listing, for our 2018 Honda CR-V. It was accurately described online. It seems to be comparable quality to the ones I took out to replace these. If I recall, they had been just as good as the stock ones when I put those in. I would say these are just as good as OEM & they feel very well made & durable. I consider them a good value for how much I saved by installing these myself & not paying a dealership. I highly recommend this

Save money with this filter bundle!

The main reason you should get this Cabin Air Filter with an Engine filter, is the value. You get both filters for the price of one. To install, it will vary of difficulty in reaching the filter compartments, so for a Civic, is just open the glove compartment and two tabs behind it, and that's it. The engine one is a little bit trickier with two metal tabs, but easy as well. As for quality, time will tell, but at first glance and overview, it looks of decent to good quality. So nothing bad to write about it. The cabin filter fit as expected. I haven't change the engine filter.
