Your 2011 Dodge Charger cabin air filter does pretty much what it sounds like it would: it filters the air that gets pumped into your cabin to for air conditioning, heating, and using the fan. Your owner's manual will tell you precisely how long to keep one for, but when the filter starts going bad you'll experience reduced air flow through your vents, excessive noise when the fans are on high, and bad smells when the climate control is on. Browse our selection of direct replacement 2011 Charger cabin air filters and find the right one for you.
