In the 2018 Ram Promaster-Cargo-Van, the engine filter helps maintain fuel economy, power, and sensor accuracy by screening intake air. The cabin filter targets pollen, dust, and odors to improve in‑cabin comfort. Each filter has a different location, media, and service goal, so replacing both on schedule preserves performance and comfort.

• Engine: upstream of throttle for clean, metered air
• Cabin: upstream of vents for cleaner interior air
• One appointment can address both: schedule service

Common signs include reduced power, lower fuel economy, rough idle, weak HVAC airflow, and musty odors.

Your 2018 Ram Promaster-Cargo-Van may feel sluggish or require more throttle when the engine filter is restricted. Inside the cabin, diminished airflow or persistent odors point to a saturated cabin element. Our Tucson service team will inspect both filters, check the intake housing, and reset seals to spec to restore performance and comfort.

• Engine symptoms: hesitation, poorer MPG, uneven idle
• Cabin symptoms: weak fan output, dust, or musty smell
• Complimentary multi‑point inspection with every visit
