Great fit for my 2024 HR-V. Easy replacement, no tools needed. Would definitely purchase again. Saved from paying outrageous pepboy fee. Could feel and smell the difference immediately after. No more allergies.

These are exact fits for my honda 2025 Honda H-RV. It was super easy to install and took me less than 5 minutes to replace my old ones and put these in. Car smells clean and no debris in the intake! Seems to be good quality (been 1 week so far)
