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!

Weird smell and reduction in air flow
The filter has a strange smell to it which I am not sure if mentioned in the description. It also seemed to reduce air flow due to the addition of the carbon pellets. Had to run the fan on full to get same amount of air flow usually occurring on 3.
