Engine Air Filter
Size: (Pack of 1)
This engine air filter fit perfectly in my 2018 Honda CR-V. No idea how it will perform but so far the Check Engine Light has not come on since installing the filter. Since there have been no problems I am happy with this filter and will likely buy again in the future. The filter does appear to be made from quality materials.

My mileage on my 2021 Honda CRV dropped 4 miles /gallon with this air filter.
Size: (Pack of 1)
My mileage on my 2021 Honda CRV dropped 4 miles /gallon with this air filter. It did fit well and was easy to install, but then I watched my average around town mileage drop from 29-31mpg to 26-27 mpg thru 2 tank fillups. The Honda repair person said this filter looked like the Honda one and was surprised when we wanted to switch it out. Granted, it looked just like the Honda filter, but the folds on the Honda one are yellowish and I have to think there has to be some difference in the texture. The average mileage went back up within 10 miles of replacing it and 3 fill ups later it has continuously maintained its original average of 29-31 with the Honda filter.

As good as Original Manufacturer Equipment.
Size: (Pack of 1)
Cheaper than having the dealer or oil change store do it. Only takes a minute to replace your existing filter for a lot less than what they want to charge you. High quality too!

Excellent Honda Alternative
Size: (Pack of 1)
I try to get everything and to keep everything as a manufacturer original on a car as possible. I will say that this filter is just as good as the Honda. The installation was very simple, you just need a screw driver to unscrew the 4 screws in the air box and this sits right in. The engine ran better and immediately got so much better MPG. I did not notice the engine struggling for air at all, if anything the car ran better. The fitment was the same size and just as good as the Honda. P.S Don't be like me. Don't hesitate to buy it. You'll love it. No questions asked!
