2018 Ram 3500 Air Filter

The engine air filter on a 2018 Ram 3500 is located in the engine bay inside the air filter housing near the front of the engine compartment.

On the 2018 Ram 3500 with the 5.7L V8, the air filter sits in a serviceable plastic housing that seals to the intake tube; it is accessible from above with basic hand tools. Technicians inspect the housing and intake tract for debris when changing the filter to protect the throttle-body and MAF sensor.

• Engine air filter sits in a sealed housing in the engine bay
• Accessible from above without major disassembly on most models
• Technician will inspect the intake housing and seals during service

The cabin air filter on a 2018 Ram 3500 is located behind the glove box inside the HVAC intake area.

Access typically requires lowering or opening the glove box to reach the HVAC intake cover and filter tray. The cabin filter protects occupants from pollen, dust and road debris and should be replaced if airflow is reduced or odors develop.

• Cabin filter accessed behind the glove box
• Protects HVAC system and passenger air quality
• Replacement often involves modest trim removal or glove-box lowering

The engine air filter cleans combustion intake air for the 5.7L V8, while the cabin air filter cleans air entering the passenger compartment through the HVAC system.

The engine air filter prevents dust and particles from reaching the intake, protecting fuel economy and horsepower. The cabin filter removes pollen, dust and odors to improve in-cabin air quality. Both filters serve different systems and require separate inspection and replacement.

• Engine filter protects combustion and sensors
• Cabin filter protects occupants and HVAC components
• Each filter is located and serviced separately on the vehicle

Common signs on a 2018 Ram 3500 include reduced engine power, decreased fuel economy, rough idle, weak HVAC airflow or a musty cabin odor.

A restricted engine air filter can reduce throttle response and load the intake, while a clogged cabin filter will lower HVAC output and introduce odors. Local conditions around Sandy—seasonal pollen and dusty roads—can accelerate clogging and merit more frequent checks.

• Reduced acceleration or engine responsiveness
• Lowered fuel economy and rough idle symptoms
• Weak HVAC airflow or musty smells inside the cabin
