Will continue to repurchase
I have purchased this product multiple times for my Honda CRV. Works great and is actually pretty easy to install. I will definitely repurchase once the time comes to replace again. Great value for the price compared to at the dealership

Good engine filter at a fair price
Worked for my 2018 Honda CR-V. Arrived quickly. Make sure you check the shape of your filter before ordering. I originally ordered a rectangular filter that Amazon said would work for my car. I was able to return it and order the correct one.
