Adequate construction (could stand to be a little better). Easy to install (remove screw on side (#1 Phillips screwdriver), remove glove box, remove filter cover, remove filter, replace). Beware of on-line instructions including the one about removing carpeting, which is not necessary. Some filters show "UP" arrow. (Up means up, not air flow) The CAF7764 shows an "air flow" directional arrow, which is DOWN. When you pull out the used filter note how it lays in the bin. The leaves and grit are on top which means air comes in from the top...so air flow is down. Overall, I give this filter a 4.5 rating because the frame seems flimsier than the one I installed in my 2015 Civic, but it is still adequate for this application, which is my 2003 Corolla beater car that just keeps on running.
What kind of vehicle do you drive? 2003 Toyota Corolla
