The air filter was great and would recommend the OEM filter. My only Complaint is that they didn’t ship it in a box but only slapped on a shipping label on to the original air filter box. It took about a week to get to me (Arizona) and the box looked really beat up and luckily the filter was still ok by the time it got to me. Recommend putting it in a box to protect it from damage.

I have a 2024 Honda HR-V. It's so difficult finding wipers that work. These were a perfect fit and the price is unbeatable for all 3! Just a heads up- There is a clear film on the blades, I didn't notice and initially thought they were horrible. Once I noticed and removed the film, they work extremely well. 10/10. Will buy again if the price stays this good!
