Engine air filters typically need replacement every 15,000-30,000 miles (or annually), depending on driving conditions and dust exposure. Cabin filters, which clean the air you breathe inside, usually last 12,000-15,000 miles. A clogged filter reduces fuel economy and engine performance, while a dirty cabin filter affects climate comfort and air quality. Castle CDJR of Naperville stocks genuine OEM filters for Jeep, RAM, Dodge, and Chrysler vehicles and can replace both in one quick visit. Call (630) 864-6683 to schedule service or ask about filter specials.
