Quality
Size: 2" x 10" x 11"
My brother put me onto these filters. Super easy to install. Also bought engine filter. One time expense. A bit pricey but cost covered if you were still buying paper ones in about 3 changes of paper ones. Will definitely pay for themselves. Highly recommend

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.
