    Works great on my 2018 Honda Civic EX
    Size: 2.0L, Size: 2.0L
    Been buying these for years. They are relatively cheap and easy to replace, so much better than getting ripped off at the dealer lmao. Compatibility and Installation - 5/5 Filtration Efficiency and Performance - 5/5 Durability and Value for Money - 4/5 - these are made to be replaced, so can't really do much about that!

    Perfect
    Size: 2.0L
    I bought this and was able to change this myself. It was simple. I got this for my 2016 Honda Civic, I don't think I ever replaced the filter in my car in the 5 years that I had it. It had a distinct smell in my car, and once I popped this bad boy in, within a day or two the smell was gone. It did make a sound for a while like I did not do it correctly, but I did, after about a week the sound went away, so everything's good. I will buy this again when the time comes
