Does Exactly What It Should
Size: CRV 2017-22 1.5L Gas
I bought the Cocoauto 2019 Honda CRV Cabin Air Filter and Engine Air Filter, and they both met my expectations perfectly. They fit just like the OEM parts and were easy to install without any hassle. The quality seems solid, and my car's airflow feels nice and clean again. No complaints here—just good, reliable filters that get the job done. Definitely worth it if you’re looking for an affordable replacement option.

Quality and Cost-effective engine filter replacement
The EPAuto GP075 Engine Air Filter is a cost-effective replacement that offers perfect fit for my car. It effectively protects the engine from contaminants, easy to install, no smell, thick, nice seal. I regularly replace the engine filter annually and expect improvement in the fuel mileage. Value for money. Happy with purchase.
