As the title says the filter wasn’t green this time (purchased 3 other times). 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. This one was grey/black with blue edge and you could tell there was charcoal embedded in it. Not sure if it will perform the same and smell the same, as I preferred the scent of the green one. The listing needs to be updated with the correct picture if the green isn’t made anymore.

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.
