2020 Jeep Wrangler Air Filter in Sandy, UT

The engine air filter on the 2020 Jeep Wrangler is located in the engine bay inside the intake/airbox assembly on the passenger side of the engine compartment.

When you open the hood of a 2020 Jeep Wrangler with the 3.6L V6, you'll see the plastic airbox that houses the element; it is secured with clips or screws. Technicians at LHM Sandy Jeep inspect the housing seal and intake for tears or debris as part of the service to prevent unfiltered air from reaching the throttle body and MAF sensor.

• Located in the engine bay inside the airbox on the passenger side
• Access usually requires unfastening clips or screws on the airbox lid
• Technician checks intake ducting and airbox seal during service

The cabin air filter on the 2020 Jeep Wrangler is located behind the glove box or inside the HVAC plenum behind the dash access panel.

Accessing the cabin filter typically requires lowering or removing the glove box on a 2020 Jeep Wrangler and pulling an access cover to extract the old element. LHM Sandy Jeep technicians check the HVAC housing for leaf or rodent debris common after seasonal trips and will inspect the blower motor inlet while replacing the filter.

• Found behind the glove box or HVAC plenum access cover
• Glove box removal or drop-down required for access
• Technician inspects blower inlet for debris during replacement

The engine air filter protects the 3.6L V6 intake from dirt for combustion; the cabin air filter protects occupants from pollen, dust, and particulates entering the HVAC system.

For a 2020 Jeep Wrangler, the engine filter sits at the intake to ensure clean air reaches the throttle body and MAF sensor, while the cabin filter sits in the HVAC pathway to clean air before it enters the cabin. Both are important: a clogged engine filter can reduce power, while a clogged cabin filter degrades airflow and indoor air quality for passengers heading to the Wasatch foothills.

• Engine filter = combustion air intake protection
• Cabin filter = HVAC/passenger air protection
• Both should be inspected during routine service visits

Common signs on a 2020 Jeep Wrangler include reduced engine power or throttle response, lower fuel efficiency, rough idle for the engine filter, and weak HVAC airflow or musty odors for the cabin filter.

If you notice hesitation during acceleration or a drop in highway mpg in your 2020 Jeep Wrangler, the engine filter or intake could be restricted. Similarly, if the HVAC blower feels weak or you detect mildew smells after spring pollen season in Sandy, the cabin filter may be saturated. Technicians at LHM Sandy Jeep inspect both filters and the MAF sensor when these symptoms appear.

• Engine symptoms: reduced power, rough idle, lower fuel economy
• Cabin symptoms: weak airflow, musty or stale odors
• Service tech inspects intake and MAF sensor for related issues

You can often replace the engine air filter yourself on a 2020 Jeep Wrangler, while the cabin filter and intake inspection may require more time or trim removal that an experienced technician can complete.

Many owners of the 2020 Jeep Wrangler with the 3.6L V6 find the engine filter is accessible with basic tools; however, cabin filter access behind the glove box can be fiddly. LHM Sandy Jeep offers inspection-focused service that includes checking the airbox seal, intake ducting, and a visual MAF sensor inspection—services DIY replacements may skip.
