Fits Perfectly. Can't beat the price. Don't Hesitate....
Actually this filter combo fits my customers car perfect. Some after market filters you have to finagle a little to make them fit, however this engine air filter and cabin filter fit perfect...Great deal for both filters.

Good purchase.
Fit perfect in my 2023 jeep grand Cherokee L. Value is great especially for a Hepa filter. Easy to install no problems at all.
