The 2004 Jeep Grand Cherokee does not come with a cabin air filter installed from the factory. However, it is possible to add one for improved air quality inside the vehicle. This guide provides essential information on locating, purchasing, and installing a cabin air filter for your Grand Cherokee.

Understanding the Cabin Air Filter

The cabin air filter is crucial for maintaining clean air within your vehicle's interior. It filters out dust, pollen, and other pollutants, ensuring a healthier driving environment. Regular replacement of this filter is recommended to maintain optimal airflow and air quality.

Cabin Air Filter Location

In the 2004 Jeep Grand Cherokee, the cabin air filter is located under the front cowl on the passenger side.

  • Installation Requirement: The Jeep did not come with a cabin air filter as standard; it must be purchased separately as a Mopar aftermarket accessory.

  • Accessing the Filter: To access the filter area, you will need to remove the weather stripping and some plastic fasteners from the cowl. This allows you to lift the cowl and expose the cabin air intake area.

Purchasing a Cabin Air Filter

When looking for a cabin air filter for your 2004 Jeep Grand Cherokee, consider these options:

  • Mopar Cabin Air Filter Kit: This kit includes all necessary components for installation, including housing and fasteners.

  • Aftermarket Filters: Various aftermarket options are available that may fit your vehicle. Ensure compatibility by checking product details.

Installation Steps

Installing a cabin air filter in your 2004 Jeep Grand Cherokee involves several steps:

1. Remove Cowl Cover: Open the hood and remove the weather stripping along the edge of the cowl. Unscrew any fasteners holding the cowl in place.

2. Access Filter Housing: Lift the cowl cover to expose the cabin air intake area. If this is your first installation, you may need to remove an inlet cover.

3. Install Filter Housing: If you are adding a filter for the first time, install the Mopar housing kit according to instructions, securing it with provided fasteners.

4. Insert Cabin Air Filter: Place the new cabin air filter into the housing, ensuring it is oriented correctly based on airflow direction indicated on the filter.

5. Reassemble Cowl Cover: Once the filter is securely in place, reattach the cowl cover and weather stripping.

6. Final Checks: Ensure everything is tightly secured before closing the hood.

Maintenance Tips

  • Replacement Frequency: It is advisable to replace your cabin air filter every 15,000 to 30,000 miles or at least once a year to maintain optimal performance.
