Excellent filter
Size: 7.5" x 8.7" x 1.4"
Perfect fit, installed easily and quickly, airflow arrow was provided, and product was well-made with high-quality materials. Box had a hole, but the filter was in a sealed plastic bag and was undamaged.

Needs modification to fit Lexus TX 350
Size: 7.5" x 8.7" x 1.4"
Does not have a proper fit on a 2024 Lexus TX 350 without some minor modification. The filter casing has a guide that it's supposed fall into one of the pleats like a notch, however, notice this filter has the white strips which I guess are added structural support. I simply cut the 2 strips on the pleat the guide falls into. The filter will not fall apart by doing this. It's a minor inconvenience that can be easily corrected yourself or simply find another filter that does not have anything blocking the pleats the entire width of the filter.
