Bosch Cabin Air Filter P/N:P3877WS
Bosch C3899WS cabin air filter for the 2015 Ram 1500 and other vehicles traps dust, grime and soot in the air entering the cabin.
Weak airflow from the vents, a musty or exhaust smell inside, or extra dust on the dash can mean this filter is worn, though a weak blower motor or a restricted air duct can be behind them too, so find out which before replacing the filter.
The vehicles it fits include the 2015 Ram 1500, the 2007-2021 Jeep Compass and the 2011-2014 Chrysler 200. If your vehicle is not named here, look up its year and model in the "Vehicles it fits" section.
