How to Change a 2015 Jeep Cherokee Air Filter: A Complete DIY Guide (Replacement Intervals, Tips & Tricks)

Replacing the air filter in your 2015 Jeep Cherokee is a straightforward, cost-effective DIY maintenance task that significantly impacts engine performance, fuel efficiency, and longevity. Performing this simple job every 15,000 to 30,000 miles, or sooner in dusty conditions, takes less than 15 minutes and requires no specialized tools – just a new filter designed specifically for your Cherokee’s engine size. This guide provides detailed, step-by-step instructions with photos to ensure you do it correctly the first time.

Understanding Your 2015 Jeep Cherokee Air Filter Options

The 2015 Cherokee came equipped with two engine choices, each requiring a different filter:

  1. 2.4L "Tigershark" 4-Cylinder Engine: This engine features a traditional flat, rectangular paper panel air filter housed within a plastic airbox.
  2. 3.2L "Pentastar" V6 Engine: The V6 uses a similar rectangular panel filter design but physically larger due to the engine's higher air requirements.

It is crucial to purchase the correct filter for your specific engine. Using the wrong filter can prevent the housing from sealing properly, allowing unfiltered air (and contaminants) to enter the engine, potentially causing damage. Always check your owner's manual or use a reliable parts lookup tool with your VIN to ensure compatibility. Popular quality brands include Mopar (OEM), Fram, K&N (including washable options), Wix, and Purolator.

Why Regular Air Filter Changes Matter

A clogged or dirty air filter creates significant problems:

  • Reduced Engine Performance: Restricted airflow starves the engine of oxygen needed for efficient combustion. This leads to noticeable hesitation, sluggish acceleration, and lack of power, particularly when merging or climbing hills. Combustion is less efficient, impacting overall power output.
  • Decreased Fuel Efficiency: When the engine computer detects inadequate airflow, it compensates by injecting more fuel to maintain power, negatively impacting miles per gallon. You'll likely find yourself filling up more frequently.
  • Potential Engine Damage: Over time, dirt, dust, and debris bypassing a failing filter act as abrasives inside the engine cylinders, accelerating wear on piston rings and cylinder walls. Consistent use of a dirty filter significantly increases long-term internal engine wear.
  • Increased Emissions: Poor combustion caused by restricted airflow leads to higher levels of unburned hydrocarbons and carbon monoxide exiting the exhaust, contributing to pollution and potentially causing your vehicle to fail emissions testing.
  • Overworking Engine Components: The engine must work harder to draw air through a clogged filter, creating additional strain over time.

Identifying a Dirty Air Filter (Visual Inspection)

Don't wait for performance issues. It's good practice to visually check your filter during oil changes or periodically:

  1. Locate the Airbox: Find the large, black plastic housing on the driver's side of the engine bay (usually near the front corner). It's connected to the intake tube going to the throttle body.
  2. Open the Airbox: For the 2015 Cherokee, the top cover is almost always secured with metal clips or simple screws. Identify the fasteners holding the top cover down.
  3. Inspect the Filter: Lift the top cover enough to see the filter element. Carefully pull the filter straight up and out if necessary.
  4. Check for Dirt and Debris: Hold the filter up to a strong light source. A clean filter will appear porous, allowing significant light to pass through the paper pleats. A dirty filter will look blocked with accumulated gray or black debris. Light will be largely blocked from passing through. Visible dirt buildup, sand, or leaves trapped in the pleats are clear signs it's time for replacement. If in doubt, replace it – filters are inexpensive compared to potential engine issues.
  5. Check the Sealing Edges: Also inspect the filter's rubber sealing edges for cracks or brittleness, which can compromise the seal within the airbox.

Step-by-Step Replacement Guide: 2015 Jeep Cherokee Air Filter

Required Tools/Supplies:

  • New, correct air filter for your engine (2.4L or 3.2L)
  • Screwdriver (usually a Phillips head – size #2 typically fits the screws if present)
  • Rag or Shop Towel (for wiping dust)
  • Safety Glasses (recommended to prevent dust falling into eyes)

Procedure:

  1. Ensure Safety: Park the Cherokee on a level surface and set the parking brake firmly. Turn the engine off and allow it to cool down slightly if recently driven. Open the hood and use the prop rod to secure it. Safety glasses prevent debris from falling into your eyes.
  2. Locate the Air Filter Housing: Identify the large, black plastic airbox assembly near the driver's side front of the engine compartment. Trace the large intake tube connected to it back towards the front grille area – this draws fresh air into the system.
  3. Identify the Fastening Mechanism: Look at the top cover of the airbox. On the 2015 Cherokee, this cover is typically secured by either:
    • Metal Clips (Most Common): These are usually metal tabs hinged on one side that flip up to release pressure on the top cover. There are often 3-4 clips holding the cover down firmly.
    • Screws: Less common on this year/model, but if present, they will be Phillips head screws located at the corners of the airbox lid. Count how many need to be removed.
  4. Release the Fasteners:
    • For Metal Clips: Firmly push on the release tab of each clip with your thumb. Rotate the clip upwards and away from the cover approximately 90 degrees. Do this for all clips securing the top of the box.
    • For Screws: Use the Phillips screwdriver to carefully remove each screw. Place them somewhere safe where they won't roll away (like a small cup or magnetic tray) to ensure they don't get lost.
  5. Lift the Airbox Cover: Carefully lift the top cover straight upwards. Some covers may have integrated components like part of the intake tube – gently rotate or move it as needed to provide clear access to the filter cavity. Avoid putting excessive strain on connected wires or hoses. Propping it up securely prevents it from falling and breaking the connectors.
  6. Remove the Old Filter: Lift the old filter straight up and out of the lower half of the airbox. Pay attention to its orientation – note which side faces upwards and how the sealing edges sit against the box. This ensures you install the new one correctly.
  7. Clean the Airbox Housing: Take the rag or shop towel and thoroughly wipe out the inside of the lower airbox housing where the filter sits. Remove any accumulated leaves, debris, sand, or dirt. Pay special attention to the sealing surface where the filter's rubber edge sits – ensure it's clean and smooth for a tight seal on the new filter. Be very gentle around any sensors projecting into the housing – avoid jamming the rag against wiring or sensor elements.
  8. Install the New Filter: Compare the old filter to the new one to confirm they are identical in size and shape. Place the new filter into the lower housing with the same orientation as the old one. Ensure the rubber sealing edge seats flat and completely against the housing surface all the way around its perimeter. Applying slight pressure evenly around the edge helps confirm it's seated uniformly.
  9. Reinstall the Airbox Cover: Carefully lower the top cover back onto the lower housing. Ensure it aligns properly and sits flush all around – a misaligned cover can prevent sealing and potentially crack plastic tabs.
  10. Secure the Fasteners:
    • For Metal Clips: Firmly press down on each metal clip until you hear or feel it "pop" or latch securely over the lip of the lower housing. Flip each clip firmly back into place, ensuring it locks down the lid effectively. Double-check all clips are fully engaged.
    • For Screws: Hand-tighten each screw back into its hole carefully to avoid stripping the plastic threads. Do not overtighten – snug is sufficient; overtightening cracks the plastic. Once finger-tight, a very light quarter-turn with the screwdriver is usually adequate to secure it.
  11. Final Check: Visually inspect around the entire edge of the airbox. Confirm the cover sits completely flush with no gaps, and all fasteners are securely engaged. Verify that no intake tubes or wiring harnesses were pinched during reassembly.
  12. Close the Hood: Safely lower the hood and close it firmly until it latches securely.

Beyond the Basic Replacement: Pro Tips & Considerations

  • Replacement Interval Factors: While 15,000-30,000 miles is a common guideline, your actual driving conditions drastically impact filter life. Driving frequently on dirt roads, gravel roads, or in sandy/salt environments requires much more frequent inspections and replacements – possibly every 5,000-10,000 miles. If you notice reduced performance or mileage sooner than expected, always inspect the filter. Check the filter sooner in heavy pollen seasons too.
  • Premium Filters vs. Standard: While standard paper filters do an excellent job, high-flow aftermarket filters (like K&N or dry-flow synthetic options) claim marginally better performance and longevity. They require special cleaning kits and must be serviced correctly. Weigh the higher initial cost against potential lifespan versus the convenience of cheaper disposable filters. Clean OEM replacement filters remain a reliable and cost-effective choice for most drivers.
  • Cabin Air Filter: Remember your Cherokee has a second air filter – the cabin air filter. This cleans air entering the vehicle's interior through the HVAC system, crucial for allergies, air quality, and preventing odors. It's located behind the glove box and requires replacement every 15,000-25,000 miles or according to the odor/ac effectiveness – a separate process from the engine air filter. Mark its replacement separately on your schedule.
  • Resetting the Maintenance Indicator (If Applicable): Higher trim levels or models equipped with an oil change reminder system might not track the air filter specifically. However, if you perform the air filter change as part of a routine maintenance interval noted in the reminder system, it's good practice to reset the reminder according to your owner's manual after completing your service tasks.
  • Avoid Common Mistakes:
    • Not Sealing Properly: The most critical step is ensuring the filter is seated correctly and the box seals tightly. A bad seal renders the new filter useless, allowing dirt to bypass it entirely. Double-check the seal after closing the housing.
    • Forcing Components: Plastic clips and housings can become brittle. Be firm but gentle with the clips and when reassembling the housing. Forcing a clip or cover can easily result in a broken tab requiring full housing replacement – a much more expensive repair.
    • Ignoring the Dirty Box: Installing a clean new filter into a filthy housing defeats the purpose. Always take a minute to clean out any accumulated debris in the lower airbox chamber.
    • Using the Wrong Filter: Double, even triple-check the part number against your specific VIN or engine size before purchasing. An ill-fitting filter can't seal correctly.

Troubleshooting After Installation

While changing the filter rarely causes problems if done correctly, here’s what to watch for:

  • Rough Idle or Stalling Immediately After Change: This strongly suggests the airbox isn't sealed. Immediately stop the engine. Turn the vehicle off, open the hood, and meticulously recheck every fastener on the airbox lid and ensure the filter is positioned correctly with the seal fully intact. A disconnected Mass Air Flow (MAF) sensor connector (located on the intake tube between the airbox and throttle body) can also cause this – inspect the connection points.
  • Unusual Engine Noise: A pronounced sucking or whistling noise near the airbox indicates a major vacuum leak, again pointing to an unsealed housing or possibly a loose connection elsewhere in the intake tract. Carefully recheck all intake tube connections leading from the airbox to the engine. Listen intently for the source.
  • Check Engine Light: In rare cases, disturbing connectors or creating a significant unmetered air leak might trigger an engine code (often P0171 – System Too Lean). Recheck work and connectors as outlined above. Consider having the code read at an auto parts store or with a simple OBD-II scanner if the light persists after verifying the airbox seal is airtight.
  • No Change in Performance: If your original performance issues persist after replacement, the air filter might not have been the sole cause. Other potential culprits could include spark plugs nearing end of life, a clogged fuel filter (less common on newer models), fuel injector issues, or problems with sensors like the Mass Air Flow (MAF) sensor or Oxygen (O2) sensors. Further diagnostic steps would be necessary to pinpoint the issue accurately – consult a trusted mechanic.
