I read off the numbers to Ecogard technical support and they said it was their filter and by the date code manufactured by a different factory.

Fits 2021 Acura TLX

Size: 8" x 10" x 2"

Amazon garage and mfg website hadn't caught up, yet: this does fit the 2021 Acura TLX SH-AWD. No problems. New way of getting access -- pinch sides of glove box and drop off of hinge. Old way required removing an access panel.
