Great product
These are very good filters and the price is great. I have found that replacing both these filters at the same time works well for me

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.
