2021 Chrysler 300 Air Filter

The engine air filter for the 2021 Chrysler 300 sits in an airbox in the engine bay, directly servicing the 3.6L V‑6 intake system.

On the 2021 Chrysler 300 you’ll find the airbox toward the front of the engine compartment; it houses the pleated engine filter that supplies the 3.6L V‑6. Technicians at LHM Sandy Jeep inspect the housing and intake tract for damage or debris during replacement.

• Located in the engine bay inside the sealed airbox
• Accessible by unclipping or removing the airbox cover
• Inspection includes intake housing and visible ductwork

The cabin air filter on the 2021 Chrysler 300 is located behind the glove box inside the passenger compartment.

Accessing the cabin filter typically requires lowering or removing the glove box on the 2021 Chrysler 300 to reach the HVAC intake housing. Our technicians inspect the housing and blend‑door areas when changing the filter to ensure proper airflow to the cabin.

• Behind the glove box inside the passenger compartment
• Often requires glove box removal or support clips to access
• Checked for pollen, dust, and leaves that affect HVAC airflow

The engine air filter protects the 3.6L V‑6’s combustion intake, while the cabin air filter cleans air entering the passenger HVAC system.

The engine filter keeps dirt and particulates out of the intake tract to protect sensors and combustion, and the cabin filter removes pollen, dust, and odors from the air you breathe inside the 2021 Chrysler 300. Both matter for performance and comfort but serve distinct systems.

• Engine filter → protects engine, MAF sensor, and fuel efficiency
• Cabin filter → filters HVAC air for occupants (pollen, dust, odor)
• Maintenance of both improves longevity and comfort in Sandy’s climate

Common signs on the 2021 Chrysler 300 include reduced engine power and weaker HVAC airflow to the cabin.

A clogged engine filter can make the 3.6L V‑6 feel sluggish, reduce fuel economy, or trigger rough idling; a clogged cabin filter typically causes reduced blower output, musty odors, or increased dust in the cabin. LHM Sandy Jeep inspects both filters when customers report these symptoms.

• Engine: reduced throttle response or lower highway economy
• Cabin: weak blower, odors, or visible dust on vents
• Inspection can reveal intake debris or collapsed/soiled filter media

You can often replace the engine air filter on a 2021 Chrysler 300 yourself, while the cabin air filter may require glove‑box removal and is sometimes easier at the dealer.

DIY replacement of the engine filter is frequently straightforward for the 3.6L V‑6 if you have basic tools and a clean work area. Dealership service adds intake and MAF visual inspection, proper OEM‑spec filter installation, and documented records, which matter for warranty and resale.

• Engine filter: generally DIY‑friendly with a screwdriver or clips
• Cabin filter: glove‑box access can be fiddly and benefits from trained help
• Dealer service includes intake/MAF inspection and disposal
