2018 RAM 3500 Air Filter in Millbury, MA

The 2018 Ram 3500 engine air filter sits inside a sealed airbox in the engine bay.

This airbox feeds the 5.7L V8’s intake and is designed for quick access and a secure seal against New England dust, salt, and moisture. During service in Millbury, our technicians open the housing, inspect the seal and intake tract, and install a Mopar-spec filter to protect the 383-hp engine. If you drive on construction sites or gravel roads, the airbox can accumulate debris faster.

• Located in the engine bay within a rectangular airbox
• Feeds the V8 intake for proper filtration under load and towing
• Seal and housing are inspected during each filter service

The engine air filter protects the V819575.7L intake, while the cabin air filter (HVAC filter) cleans the air you breathe inside the truck.

The engine filter sits in the under-hood airbox to keep grit out of the combustion chambers, supporting torque and fuel economy. The cabin filter, when equipped, sits in the HVAC path to reduce dust and pollen entering the cab. In Central Massachusetts, spring pollen and winter road debris make both filtration paths important for comfort and performance.

• Engine filter: under-hood airbox for combustion air
• Cabin filter: HVAC airflow to the passenger compartment
• Mopar-spec media and fitment help maintain seal integrity

Common signs include reduced power, lower fuel economy, and rough idle for the engine; weak HVAC airflow and musty odors for the cabin.

On a 2018 Ram 3500, a dirty engine filter can choke the V8, especially noticeable when towing or climbing grades around Worcester County. For the cab, dust and pollen can load the HVAC filter, cutting airflow and creating odors. If you see dark, debris-laden filter media or feel sluggish throttle response, its time for inspection.

• Engine: hesitation, poorer MPG, darker filter media
• Cabin: reduced vent flow, increased fogging, odors
• Check more often after off-road, dusty, or winter plow use

The engine filter is generally DIY-friendly, while dealer service adds OEM-spec parts plus intake and sensor inspections.

Most owners can open the airbox and swap the engine filter with basic tools. At Herb Chambers Chrysler Dodge Jeep RAM FIAT of Millbury, we use Mopar filters, verify airbox sealing, check the intake tract, and perform a visual MAF/MAP inspection1for trucks that work hard, these checks prevent dust ingress. If your cab is equipped with an HVAC filter, trim access may take extra care.
