What’s the Difference? Engine vs. Cabin Air Filters
Your Grand Cherokee has two different filters for two different jobs, and it’s good to know which is which.
- Engine Air Filter: This filter protects your engine. It traps dirt, bugs, and debris before they can get sucked into the engine . A clean filter ensures your engine gets the air it needs for efficient combustion, which affects performance and fuel economy.
- Cabin Air Filter: This filter is for you and your passengers. It cleans the air that comes through your vehicle’s heating and air conditioning system, removing dust, pollen, and other contaminants from the cabin .
DIY Guide: Replacing the Engine Air Filter
This is the filter that lives under the hood. The process is nearly identical across many Grand Cherokee models (1999–2024) .
What You’ll Need:
- New engine air filter (make sure it’s the right one for your engine)
- A flathead screwdriver (sometimes helpful, often not needed)
- A clean rag or shop towel
Step 1: Open the Hood and Find the Box
Pull the hood release handle inside the cabin, then unlatch the hood and prop it open . Look for the large, rectangular plastic box near the front of the engine bay—usually on the passenger or driver’s side . This is the air filter housing.
Step 2: Open the Air Filter Housing
The housing is held closed by either metal clips or screws, depending on your model year.
- For models with clips: Simply unlatch all four metal clips that hold the top and bottom of the housing together .
- For newer models (2022+): You might need to loosen the fasteners/screws on the cover with a screwdriver .
Once the clips are undone or the screws are loose, gently lift the top half of the housing. On many models, you don’t need to remove it completely; you can just swing it aside .
Step 3: Remove and Replace the Old Filter
Lift the old filter out of the housing . Take a moment to wipe out any dust or debris from the bottom of the box with a rag .
⚠️ Pro Tip: Before you install the new one, place a clean rag over the air intake opening to prevent any dirt from falling into the engine .
Position the new filter into the housing. Make sure it sits flat and snug . Then, close the cover and secure all the clips or tighten the screws.
⚠️ Safety Reminder: Do not overtighten the screws on the air filter cover! This can damage the housing .
DIY Guide: Replacing the Cabin Air Filter
This filter is tucked away behind the glove box. While the location is standard for many models, the process can vary slightly. This guide covers the most common method for 2011–2025 Grand Cherokees .
What You’ll Need:
- New cabin air filter
- Gloves (optional)
Step 1: Access the Glove Box
Open your glove box. You’ll need to disengage the side stops to let it swing all the way down. On many models, you simply pinch the sides of the glove box inward to release it . On others, you may need to remove a damper or stopper.
Step 2: Remove the Filter Cover
Once the glove box is out of the way, you’ll see a plastic cover for the cabin air filter housing. Pinch the clip or tab on the side to release it and pull the cover off .
Step 3: Replace the Cabin Air Filter
Pull out the old filter. Before you slide the new one in, take note of the airflow arrow on the side of the filter. For the Grand Cherokee, the arrow must point down . Slide the new filter in with the arrow pointing correctly. Reattach the cover and push the glove box back into place.
When Should You Change These Filters?
Regular maintenance is key to a happy Jeep. Here’s a simple schedule to follow:
- Engine Air Filter: Every 12,000–15,000 miles or once a year. If you frequently drive on dusty trails, check it more often .
- Cabin Air Filter: Every 15,000–30,000 miles. If you notice a musty smell when you turn on the A/C or a weak airflow, it’s time for a change .
