2018 Ram 2500 Air Filter

The 2018 Ram 2500 engine air filter sits inside a sealed airbox in the engine bay, ahead of the 6.4L V8 intake.

Lift the hood and find the intake airbox; it opens via clips or screws to access the rectangular filter element. Ensure the filter seals evenly around the housing before re-closing the lid. During service in Tucson, our team also checks the intake ducting for dust leaks and inspects the mass airflow (MAF) sensor area. If you prefer professional care, you can schedule service and we’ll handle the inspection and replacement with Mopar parts.

• Engine: 6.4L V8 (410 hp/429 lb-ft) requires unobstructed intake flow
• Airbox access typically involves clips or screws—no reprogramming needed
• Book a schedule service appointment for OEM-spec installation

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

Both filters serve different systems: one preserves combustion efficiency and power; the other improves in-cabin air quality and HVAC performance. Using Mopar-spec filters helps ensure a proper seal and fit in your 2018 Ram 2500. If you’re unsure which filter needs service, our complimentary multi-point inspection can identify it during your visit in Tucson.

• Engine filter: performance and fuel-economy protection
• Cabin filter: reduces dust, pollen, and odors in the cabin
• OEM Mopar parts match Ram housings for correct fitment

Common signs include reduced power, lower fuel economy, or a rough idle for the engine filter, and weak HVAC airflow or a musty odor for the cabin filter.

Your 2018 Ram 2500’s 6.4L V8 relies on clear airflow for consistent performance, especially when towing or hauling. Cabin filter issues often show up as foggy windows that clear slowly or increased fan noise. In Tucson, our technicians can confirm the cause, check the intake housing, and install Mopar filters that meet Ram specifications.

• Engine symptoms: sluggish acceleration, irregular idle quality
• Cabin symptoms: reduced vents airflow, lingering odors
• Ask for a free multi-point check with any schedule service visit

Yes—most owners can DIY the engine filter with basic tools, while the cabin filter often requires glove box access and careful trim handling.

DIY works if you’re comfortable opening the airbox and seating the filter properly. Dealer service adds an intake-housing inspection, a visual MAF check, correct Mopar filter selection, proper disposal, and a complimentary multi-point inspection. If you prefer professional care or want everything verified by OEM-trained technicians, book a schedule service appointment in Tucson.

During a 2018 Ram 2500 air filter service, our factory-trained technicians perform a focused sequence to protect both performance and comfort.

Next, we inspect the cabin filter, access the HVAC cowl/glove-box area as applicable, and replace the element if needed to restore airflow. A visual MAF sensor and intake snorkel check helps prevent drivability issues, and we confirm the airbox is fully sealed.
