How to change an engine air filter: step-by-step
Park and shut off the vehicle
Park on a level surface, turn off the engine and allow engine components to cool before beginning work.
Locate the air filter housing
Open the hood and locate the engine air filter housing.
In many Chrysler, Dodge, Jeep® and Ram Brand vehicles, the air filter housing is a black plastic box connected to the engine intake system.
Open the housing
Release the clips, fasteners or screws securing the air filter housing.
Carefully lift the cover according to your vehicle's service procedures.
Inspect the air filter housing
Inspect the air filter housing for accumulated dirt, leaves, insects or debris.
Wipe away any loose contaminants using a clean cloth. Avoid allowing debris to enter the intake system.
Install the new engine air filter
Place the new filter into the housing in the same orientation as the original filter. Ensure the filter sits properly within the housing and that all edges are seated correctly.
Reinstall the housing cover
Reattach the housing cover and secure all clips, fasteners or screws. Confirm that the housing is fully sealed before closing the hood.
Common engine air filter replacement mistakes
Even though replacing an engine air filter is often a straightforward maintenance task, a few simple mistakes can affect the installation.
Installing the engine air filter incorrectly
Engine air filters are designed to fit a specific way within the housing. Installing the filter in the wrong orientation may prevent it from sealing properly.
Not securing the housing cover
After installing the new filter, make sure all clips, fasteners or screws are properly secured. A loose housing cover can allow unfiltered air to bypass the filter.
Leaving debris in the air filter housing
Leaves, dirt and other debris can collect inside the housing over time. Before installing the new filter, take a moment to wipe away any loose contaminants.
Using the wrong replacement air filter
Engine air filters are vehicle-specific. Always verify fitment before installation to help ensure proper fit and compatibility with your vehicle's intake system.
Troubleshooting after installation
If you encounter issues after replacing your engine air filter, perform a quick inspection before driving.
Air filter housing won’t close properly
After installation, the housing should close evenly and completely. If it doesn’t, remove the housing cover and confirm that the filter is fully seated within the housing. A filter that is not positioned correctly may prevent the cover from closing completely.
Reduced engine performance
If the vehicle feels sluggish or doesn't respond as expected during acceleration, double-check that the replacement filter is the correct part for your vehicle and that it was installed in the proper orientation.
I hear strange noises or rattling under the hood
If you hear a whistling, hissing or excessive air intake noise after installation, the air filter housing may not be fully sealed. A loose air filter housing cover or unsecured fastener may also create rattling noises or vibrations while driving.
Inspect the housing and confirm all retaining clips and hardware are fully engaged.
