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.

Reliable part
The price of this item was a bit of a shock. A good one though. I gave it to my mechanic, he installed it with no problems. Runs just fine. Would buy again
