    Easy to install
    Very easy to install this engine filter and checking the compatibility with my car was super easy too. I took me about 5 minutes to look up, learn, and install this. Loved that I saved money by installing it myself instead of getting overcharged but the shop. Works for a 2017 Honda Fit.
