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.
