Fists a perfect in my 21 GCL
Great quality and very sturdy. Perfect fit in my 21 GCL. I will be interested in seeing if it cuts down on the amount of dust in the car.

Won’t fit.
Does not fit 2023 Jeep Grand Cherokee Laredo . If it could be forced into slot it would be difficult to remove. The air flow direction is not marked on the filter or packaging.

Excellent fit for my 2023 Grand Cherokee limited l
Not sure why others are saying airflow is decreased or it doesn't fit if they apply it to the correct vehicle. I have a 2023 Grand Cherokee Lmited L and it took me all of 5 minutes to change out the filter and I have to say, this filter is much better quality than the Mopar filter that was in there. There's absolutely no decrease in air flow and it's like a custom fit in the space. The hardest part about the entire process was emptying out the darn glove box!
