    Good quality fits 2025 Civic Hybrid
    The filters are good quality. I did not find any instructions, but then again, the tube is full of them. Compaitble with 2025 Civic Hybrid. The engine filter have a bit of a chemical smell, but the air cabin filter does not. The cabin filter has an interesting yellow color.

    Quality filters for a decent price
    The engine filter is model # JMAJ20. I am not sure of the cabin filter model #. I have a 2026 Honda CRV Hybrid 2.0L Sport Touring. These should fit as almost everything matches between the 2025 and 2026. I have not yet needed to swap the filters in the new vehicle. These filters will be stored for future replacement. The filters appear to be well made. This is a decent price fortwo filters. The engine filter's gasket is a little wavy but it should be ok to form fit once inserted into the car. The engine filter is in a retail box without a plastic wrapper but the cabin filter is just a plain cardboard box inside a plastic wrapper. This might be challenging to remember what is in the box later once the filter needs to be replaced unless I write the information onto the box. I am unsure if the lack of a wrapper for the engine filter will affect the filter while stored. I did not notice a smell to these but I am not sensitive to smell. I would get these again.
