Does Not Fit
Size: 2" x 10" x 11"
This does not fit the 2024 Accord Sport Hybrid. It is approximately 1/4 inch too wide on each side (1/2 inch total), will not fit in the opening. Car was entered into the system and purchase page says this is correct and will fit.

Perfect fit! So grateful for you carrying this and the great price. My AC has been out for about a year but when I replaced this, it now works again! Had no idea there was such a thing.
