Quality filter
Nice filter, fits perfect in the WL model (not the WK!) I will buy this one again, far superior to the OEM filter from the dealer!

I added a little bit of foam weather stripping for a more sealed fit.

Insanely great cabin air filter!
This filter absolutely blows away the Mopar cabin filters. It has foam around the outside which sealers the filter to the housing. Will definitely buy again!

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.
