Function: The cabin filter is located near the internal air intake of your vehicle and filters the air you breathe while driving. It helps reduce pollution, pollen, and other airborne particles, as well as small debris, contributing to improved air quality inside the vehicle. Fitment: Designed as a replacement for Ram 1500. It is recommended to replace the cabin filter every 12,000 to 15,000 miles. More frequent replacement may be necessary if driving often occurs on unpaved roads or in areas with high levels of air pollution. Replace Part Number: 68406048AA. A worn or dirty cabin air filter may cause unusual odors from the vehicle’s interior vents, such as a musty, dusty, or unpleasant smell. If this occurs, filter replacement is advised. Installation: The filter can be installed by carefully cutting an opening along the ridge of the cover using a utility knife, ensuring the size matches the filter. Slide the filter into the opening and secure the new cover, making sure the tabs lock into place. What's Included: 1 cabin air filter and 1 filter access door. Minor adjustments, such as trimming the opening or plastic slot, may be required for proper fitment.
