Frequently Asked Questions

11 common questions answered

Where is the engine air filter located on a 2018 Ram 2500?

The 2018 Ram 2500 engine air filter sits in a rectangular airbox inside the engine bay, typically on the passenger side near the fender.

Open the hood and look for a large plastic housing connected to the intake tube leading to the 6.4L V8. Release the clips or screws to access the filter. Our technicians in Tucson verify the seal, housing condition, and intake routing during every replacement.

  • Rectangular airbox with metal clips or screws
  • Connected to intake tube feeding the 6.4L HEMI V8
  • Seal and housing checked during service in Tucson, AZ
What’s the difference between an engine air filter and a cabin air filter on a 2018 Ram 2500?

The engine air filter protects the 6.4L V8’s intake from dust, while the cabin air filter cleans HVAC air for you and your passengers.

The engine filter helps maintain power and fuel economy by keeping debris out of the combustion air stream. The cabin filter traps dust, pollen, and particulates that enter the ventilation system. In Tucson’s dusty climate, both can load faster and should be inspected regularly.

  • Engine filter: performance and engine protection
  • Cabin filter: HVAC airflow and interior air quality
  • Both inspected during service with OEM-spec parts
What are the signs of a clogged air filter on a 2018 Ram 2500?

Four common signs are reduced power, lower fuel economy, rough idle, and weak HVAC airflow or musty odors.

For the 6.4L V8, a clogged engine filter can limit intake air and dull throttle response. A dirty cabin filter restricts blower output and may carry a dusty or damp smell. Tucson’s dust and seasonal pollen can accelerate clogging, so periodic checks help prevent drivability and comfort issues.

  • Engine: sluggish acceleration, decreased MPG
  • Engine: uneven idle or intake hiss
  • Cabin: weak vents, odors, more windshield haze
Can I replace the air filter on my 2018 Ram 2500 myself, or should the dealer do it?

Yes, the engine filter is typically DIY-friendly; the cabin filter often requires glove box access and careful trim handling.

Many owners can swap the engine filter by unclipping the airbox and dropping in an OEM-spec element. The cabin filter sits behind the glove box on most Ram trucks, which may involve stops or tabs. Dealer service adds housing inspection, MAF/intake checks, and proper fitment to prevent leaks.

  • DIY engine filter: basic tools, minutes to complete
  • Cabin filter: glove box access and correct orientation
  • Dealer adds sealing, MAF, and intake checks
