What you need to know before you start
Your Jeep Grand Cherokee has an engine air filter that traps dust, pollen, and debris before air reaches the engine. Over time it clogs and restricts airflow, which makes your engine work harder and wastes fuel. Replacing it yourself takes about 10 to 15 minutes and costs $15 to $40 for the filter itself — far less than a shop visit.
The exact location and type of filter depends on which model year and engine you have. A 2011–2021 Grand Cherokee uses a different filter housing than a 2022 or newer model. Knowing your year and engine size before you buy a replacement filter prevents buying the wrong part.
Key Takeaways
- Engine air filters on Grand Cherokees are located under the hood in a plastic box, usually on the driver's side or near the engine's top.
- Most filters need replacement every 15,000 to 30,000 miles, though dusty driving conditions mean you may need to replace yours sooner.
- You will need only basic tools — usually just your hands or a screwdriver — to open the filter housing and swap the old filter for a new one.
- Buying the correct filter for your model year and engine size prevents installation problems and ensures proper airflow to your engine.
Locating the air filter on your Grand Cherokee
Open your hood and look toward the driver's side of the engine compartment. On most Grand Cherokees, the air filter housing is a black plastic box roughly the size of a toaster. On 2011–2021 models, it typically sits near the top of the engine or along the side closest to the windshield. On 2022 and newer models, the housing may be positioned differently, so check your owner's manual if you cannot spot it when ready.
The housing has a lid held down by clips or bolts. If you see a large hose running from the housing toward the engine, you are looking at the right place — that hose carries filtered air into the engine. Trace it backward to confirm you have found the filter box.
Removing the old filter
Once you have located the housing, open it by unclipping or unbolting the lid. Most Grand Cherokees use plastic clips on either side of the box — squeeze or pry them open with your fingers or a flat screwdriver. Some models use bolts instead; if yours does, use a socket wrench or screwdriver to remove them. Set the bolts or clips aside where you will not lose them.
Lift the lid straight up and set it aside. The old filter will be sitting inside, usually pleated white or yellow paper. Lift it out and dispose of it. Look inside the housing for any loose dirt or debris and wipe it out with a dry cloth or paper towel. Do not use water or compressed air, as moisture can damage the housing or leave residue.
Installing the new filter
Before you install the new filter, check that it matches your model year and engine size. The filter part number should be printed on the box or the filter itself. Compare it to your owner's manual or the part number listed on the old filter to confirm it is correct.
Slide the new filter into the housing with the pleated side facing up (or in the direction the old one was facing). Make sure it sits flat and does not tilt or bunch up. The filter should fit snugly but not require force. Close the lid and reattach the clips or bolts firmly — the seal needs to be tight so unfiltered air does not bypass the filter.
Knowing when to replace your filter
Most manufacturers recommend replacing the engine air filter every 15,000 to 30,000 miles. If you drive in dusty conditions — unpaved roads, desert areas, or high-pollen seasons — you may need to replace it more often, sometimes as frequently as every 10,000 miles. Check your filter visually every oil change; if it looks dark or clogged, replace it even if you have not reached the mileage interval.
A clogged filter reduces fuel economy and can make the engine feel sluggish during acceleration. If you notice either of these symptoms, pull the filter out and hold it up to a light. If you cannot see light through the pleats, it is time for a new one.
Choosing the right replacement filter
Jeep Grand Cherokee filters vary by model year and engine type. A 2015 model with a 3.6-liter V6 engine uses a different filter than a 2020 model with the same engine size, because the housing design changed. Your owner's manual lists the correct part number, or you can provide your vehicle identification number (VIN) to an auto parts store and they will look up the right filter for you.
Aftermarket filters from brands like Fram, Bosch, and K&N are widely available and cost $15 to $40. OEM (original equipment manufacturer) filters from Jeep dealers cost more but are may provide to fit. For most owners, a quality aftermarket filter works just as well and saves money.
Frequently Asked Questions
Can I drive with a dirty air filter?
Yes, but you should not. A clogged filter reduces airflow to the engine, which wastes fuel and can cause rough idling or hesitation during acceleration. Replacing it is inexpensive and takes minutes, so there is no reason to delay.
Do I need to replace the cabin air filter at the same time?
The cabin air filter (which cleans air inside the passenger compartment) is separate from the engine air filter and has its own replacement schedule. Check your manual for the cabin filter location and interval. Many owners replace both at the same time for convenience, but they are not connected.
What if the new filter does not fit in the housing?
Stop and double-check the part number against your manual or the old filter. If the numbers do not match, you have the wrong filter for your model year or engine. Return it and get the correct one. Forcing a filter that does not fit can damage the housing or leave gaps that let unfiltered air into the engine.
Is there a difference between cheap and expensive air filters?
Most filters do the same job — trap particles and let air through. Premium filters may claim longer life or better airflow, but for normal driving, a standard filter from a reputable brand works fine. The most important thing is replacing it on schedule, not which brand you choose.
